  • 14. TITANIUM SPONGE
    • KMML has taken a big leap into aerospace working towards value addition of its Titanium Tetra Chloride with the launch of Titanium Sponge Plant
    • Titanium Metal derived from Titanium Sponge finds use in a variety of fields like aerospace industry, atomic energy, defence etc
    • Due to its lightweight, higher strength, non-corrosive and non-reactive quality, it finds use in surgical and orthopaedic transplants
    • KMML’s foray into the
    • production of Titanium Sponge
    • makes it the first and only
    • company in India, and the
    • 7 th country in the world,
    • to produce Titanium Sponge

  • 15. NANOTITANIUM DIOXIDE
    • Nanomaterials - Particles with Dimension in the range of 1-100 Nm
    • The Average Density and Coordination between the neighbors changes as Crystal Size is reduced, hence properties of Nanomaterials differ from Parent Material
    • As Size Decreases the following properties increases
    • - Hardness & Strength of Metals and Alloys
    • - Electrical Conductivity in Ceramics and Magnetic Nanocomposites
    • Nanomaterials finds application mainly in Nanoelectronics, Catalysis, Semiconductors, Coatings, Ceramics Etc

  • 16. NANOTITANIUM DIOXIDE – GLOBAL OVERVIEW
    • Recently there has been a surge in Nano TiO2 products in the international arena
    • The Global Production of Nanotitanium Dioxide is Approximately 5000 Tonnes/Annum
    • In India Currently 10-20 tonnes of Nanotitanium Dioxide is Imported Annually for Various Applications

    • Particle Size
    • - Pigmentary TiO2: 250 - 350 NM
    • - Nano TiO2: 20 – 50 NM
    • Pigmentary TiO2 - Scatter visible Light and absorb UV light
    • Nano TiO2 - Scatter and reflect UV light effectively and transmit Visible light through the crystal
    NANOTITANIUM DIOXIDE – PROPERTIES Spreading Splendour
  • 23.
    • Nanotitanium Dioxide have higher Surface Area and high Photocatalytic Activity,
    • Heavy Surface Coatings are required to suppress the Photocatalytic Activity
    • For Coating applications, Nanorutile is surface coated with Silica, Alumina and Zirconia
    • Nanoanatase has higher Photocatalytic Activity, hence used in Self Cleaning Paints Etc

    • NANO TIO2 AT KMML
    • KMML R&D has developed a process for making Nanotitanium Dioxide from Titanium Tetrachloride
    • Indian Patent has been filed for the process developed (application Number: 5789/Che/2010 Dated 5/3/10)
    • The Process involves scrubbing of Titanium Tetrachloride with water to make Titanium Oxy Chloride and then precipitating Nano Tio2 from Oxy chloride Solution at low temperature by Water addition
    • Thus precipitated Nano TiO2 is washed, filtered, calcined and fluid jet milled to obtain the final product
