  1. 1. Neoker, S.L. Single crystal pure alumina fibers1st Spanish Award on Innovation on AdvancedMaterials and Technologies
  2. 2. Neoker alumina fibers: purity, strength, chemical stability, thermal resistance.OUR PRODUCTNEOKER, S.L. is presently the only world producer of single-crystal aluminafibers. This tiny filamented material shows a unique combination of high me-chanical strength and outstanding thermal and mechanical stability. Therefore,single crystal pure alumina fibers are extremely high performance materials,and thus they are the perfect candidates to be employed as reinforcing phase inevery high added-value Advanced Composite.Traditionally, the industries more interested in these materials were the automo-tive, aeronautics and military industries, but every day new applications are Scanning Electron Microscope (SEM) image,emerging requiring novel high performance reinforcing materials. For most of showing the basal structure of Neoker fibers.them, Neoker alumina fibers do offer an advanced technological solution.Main applications:-Metal Matrix Composites (MMCs)-Ceramic Matrix Composites (CMCs)-Isolation solutions for very high temperatures-Filters for aggressive environments.-Other.

  3. 3. Neoker alumina fibers: purity, strength, chemical stability, thermal resistance. PROPERTIES Chemical composition >99.7% -Al2O3 Tensile Strength >6 GPa Aspect Ratio >103 Electrical Insulator Melting point 2050ºC Flammability, Fresh Water, Organic Solvents, Oxidation, Environmental Resistance Sea Water, Strong Acid, Strong Alkalis, Wear Drops at the end of fibers are due to Vapor-Liquid- Solid (VLS) growth. VLS deposition is characteristic of the Neoker technology. VLS drops are eliminated via leaching, so the purity can be controlled on customer’s demand.2
  4. 4. OUR COMPANYNeoker, S.L. is a spin-off company of the Institute of Ceramic Ma-terials of Galicia (I.C.G.), associated with the Spanish University ofSantiago de Compostela (U.S.C.). This initiative has been spear-headed by the same scientists who developed the novel technologyfor the synthesis of single crystal pure alumina fibers. The Projecthas been supported by the Spanish Ministry of Industry and Tech-nology through the NEOTEC Program. Two well-known andhighly prestigious capital risk investors, Unirisco S.C.R and Unin-vest S.G.E.C.R, joined in as partners of NEOKER and guaranteedthe success of the project in its initial phase. Altogether, the uniqueIP on novel technologies for the synthesis of advanced materials,the long-standing technical and managerial experience of its corpo-rate staff, and the strong financial support from both state and pri-vate sources makes NEOKER a solid project with a bright future.We are proud of our innovative spirit. Our goal is to work in close Neoker’s technology allows the continuous productioncollaboration with our customers to find efficient and competitive of fibers on special ceramic substrates.solutions to their needs in advanced materials. Wecommit ourselves to maintain our products under themost rigorous quality standards, thus making them first-choice materials for ad-vanced applications. Santiago de Compostela Spain Neoker production facilities are located near Santiago de Compostela, in the north- ern-west corner of Spain. 3
  5. 5. Neoker alumina fibers: purity, strength, chemical stability, thermal resistance. ADVANTAGES Inorganic fibers are widely employed as strengtheners in high- temperature composites, both in CMC’s (Ceramic Matrix Composites) and MMC’s (Metal Matrix Composites). High performance reinforcements allow to improve fracture toughness in ceramics. When included in metals, they increase hardness, strength and maximum use temperature, giving rise to lighter and highly cost- effective advanced materials. Polycrystalline alumina fibers are usually alumina grains bonded with the aid of a secondary phase, that is responsible for the low performance of many of them. Even when purity is around to 99% alumina, grain growth in non-crystalline fibers, at high temperatures, becomes an in- convenient. Neoker fibers do not present grain growth, because they are single crystals. Their composition is only alfa-alumina, without any secon- dary phase. Another advantage is that they have a preferential growth along the c axis, which improves their resistance to creep.

  6. 6. Neoker alumina fibers: purity, strength, chemical stability, thermal resistance. ADVANTAGES IN COMBUSTIÓN ENVIRONMENTS Al2O3 fibers are highly advantageous over non oxide fibers, which lose their properties through oxidation at high temperatures (due to wa- ter steam). Neoker’s fiber performance even improve that of single crystal SiC whiskers, for use in MMC’s, mainly when used in atmos- pheres containing water steam at high temperatures. Titanium matrix composites, Inconel matrix composites and other super -alloys can reduce their creep and fatigue at high temperatures by incor- porating Neoker’s fibers, while at the same time reduce their weight. Using Neoker alumina fibers brings improved mechani- cal characteristics in your materials, even at high tem- peratures and in combustion environments, and means saving money in terms of reduced weight. 5
  7. 7. Neoker alumina fibers: purity, strength, chemical stability, thermal resistance. OTHER ALREADY EXISTING ADVANTAGES FIBERS. The properties of polycrystalline competi- tors are governed by deleterious secondary phases, like the black links in the chain at the left image. Even with per- centages of secondary phases well below 1%, the performance of polycrystalline fibers is dramatically limited by the proper- ties of these deleterious components : it’s the weakest link theory effect. Neoker’s whiskers single crystal struc- ture reproduces the effect of a chain with all links made out of alumina. In practice, this fact means that their high temperature performance and mechanical properties improve, by a factor of 1000 times, those of their polycrystalline competitors. There’re no weakest links!.6

  13. 13. NEOKER, S.L. A Contender for “World’s Best Technology” Title Production of Alumina Fibers Technology at the 2009 WBT Arlington, TX – Neoker, S.L. was among the top technology innovators from across the nation and around the world presenting at the March 24-25 WBTshowcase in Arlington, Texas. Neoker’s technology, which allows the production of novel alumina single crystal fibers, was rigorously screened and mentored by WBTshowcase commercialization experts to present to an audience including over 100 venture investors and Fortune 500 licensees. “The revolutionary nature of the technologies presenting at the WBTshowcase makes it a must-attend event for investors and licensing scouts,” said Paul Huleatt, WBTshowcase CEO. The WBTshowcase is the nations premier event showcasing the largest collection of undiscovered technologies emanating from the world’s leading universities, labs and research institutions. Each year, just one of the WBTshowcase’s carefully selected presenters receives the "Best of Show" award. Mr. Huleatt highlighted that the companies groomed to present at the WBTshowcase leave with new knowledge and contact to take their tech- nologies to market and beyond. The 2008 World’s Best Technologies Showcase brought together over 75 world-class deals and attracted over 450 attendees including over 100 bonafide investors and Fortune 1000 licensees. According to Mr. Huleatt, approximately 1/3 of past WBTshowcase presenters have gone on to secure venture capital or a licensing/strategic partnering agreement with a Fortune 500 company. To date, past presenters have raised over $400 million in first (or next) round venture capi- tal. ABOUT WBTshowcase The WBTshowcase is the premier event in USA showcasing the largest collection of undiscovered technologies emanating from the world’s leading universities, labs and research institutions.12
