The Influence of RF Substrate Materials on Passive Intermodulation (PIM)Manfred Huschka
The document discusses how the choice of RF substrate materials can influence passive intermodulation (PIM) in components. It states that the substrate material, copper foil type, and surface protection all impact PIM levels. Selecting materials with tightly controlled dielectric properties, very low profile copper foils, and protective coatings can minimize PIM. Choosing the most suitable combination of these materials is important for achieving the lowest possible PIM.
Barium titanate (BaTiO3) doped with rare-earth elements (REE) is used as dielectric in the manufacture of multilayer ceramic capacitors (MLCCs). The most common REE oxide employed as dopant for this application is Y2O3. The behavior of the Y3+ in the BaTiO3 structure depends on its concentration and the sintering conditions, among other factors, which can induce the formation of secondary phases that are a potential cause a detriment to the electrical properties of BaTiO3. The purpose of this work is to perform a phase characterization of BaTiO3 doped with different concentrations of Y2O3, validating its possible contribution to the formation of secondary phases. The role of Y2O3 was evaluated on two kinds of raw materials. The first one is pure BaTiO3 (< 100 ppm Y) and the second kind is a commercial formulation designed for MLCCs known as X7R (-55°C and 125°C, 15% tolerance), which among other elements, already contained 1 wt% of Y2O3. High concentrations of Y2O3 (1% up to 20 wt%) were used aiming to promote structural changes, and even the formation of secondary phases in amounts suitable to be detected by X-ray diffraction. Heat treatment of powder and sintering of ceramics (powder compacted at 2 MPa) were conducted in air (1310°C in air for 3 h, two steps: 1350°C then 1150°C 15 h). A phase transition from tetragonal to a mixture of tetragonal and cubic was observed as Y2O3 concentration increases in the thermally treated powder and in the corresponding ceramics. Commercially formulated powder showed higher densification than pure BaTiO3, and produced cubic structure at higher Y2O3concentrations. The phase Ba6Ti17O40is detected in the 20 wt% Y2O3-doped sample.

Samarium hexaboride both conductor and insulatorRichard Castle
A research team from the University of Cambridge discovered that samarium hexaboride has unique electrical properties. It acts as both a conductor and insulator depending on temperature - the surface is conductive like a metal at low temperatures, while the interior is insulating. This challenges traditional understandings of materials as either purely metallic conductors or insulating insulators. The research, led by Professor Suchitra Sebastian, found samarium hexaboride is a good room temperature conductor that becomes a topological insulator with a complex, special electron interaction in its interior at low temperatures.

Hydrogen fuel cells have advantages but producing, storing, and transporting hydrogen poses real challenges. Aluminum air batteries have high energy density but low power density and issues with aluminum's chemical properties. Flow batteries have higher energy density than traditional batteries but still low densities that limit their use to energy storage stations rather than vehicles. Graphene batteries can charge and discharge fast but have short lifespans in experiments so far.
Zegen Metals&Chemicals Limited provides a comparison of 4 energy storage systems:
1) Hydrogen fuel cells have advantages of being environmentally friendly but challenges in hydrogen production, storage, transportation due to its high pressure and low temperature requirements.
2) Aluminum air batteries have high energy density but low power density, and challenges in guaranteeing safe and stable performance of aluminum.
3) Flow batteries have higher energy density than normal chemical cells but still have low energy density limiting their use to energy storage stations not vehicles. Recent research increased electrolyte density but is still experimental.
4) Graphene batteries can increase capacity but in experiments provide only short battery life despite fast charging and discharging.

Thallium metal
Thallium is soft gray metal. Using newly developed method of flame spectroscopy, thallium
produces a notable green spectral line. Thallium tends to oxidize to the +3 and +1 oxidation states
as ionic salts. The +3 state resembles that of the other elements in the thallium’s group(boron,
aluminum, gallium, indium). The +1 state, which is far more prominent in thallium than the
elements above it, recalls the chemistry of alkali metals.Thallium is refined from zinc scrap.
Approximately 60-70% of thallium production is used in the electronic industry, and the
remainder is used in the pharmaceutical industry and in glass manufacturing. It is also used in
infrared detectors.

Mercury
Mercury is a kind of fluid metal in normal temperature with fluidity. It get heaviest density in all
liquid. Many different metal could dissolve into amalgam in mercury, thallium most, its dissolve
42.8% when 18 degree Celsius, iron the least, 1.0*10-17
%, so mercury could be packed with
ironware.
Chemical property of mercury is stable, which is not easy to be oxidized and corroded. When
activated with sulfur, HgS is produced, when activated with chlorine, HgCl3 or Hg2Cl2.Standard
electric potential is +0.86, electrochemical equivalent is 7.483 gram/ampere.hour.
Mercury and the compound get many kinds of uses, like chemical, electric appliance, instrument,
medicine, metallurgy, military, new technique and so on.
In chemical industry, mercury cathode electrolyze salt solution into chlorine and caustic soda. It is
also used as substitute for water as heating medium or thermostat of higher temperature in
distillation equipment. Mercury is widely used in electric appliance and equipment, as mercurial
thermometer, gyroscope or pressure capsule for airplan or steamer sailing at night. It could be used
in production of different electric switch, mercury lamp, mercury rectifier, oscillator, mercury
battery and primary battery and so on. Mercury also could be sued as coolant and anti-radiation
material in atomic reactor. Considering mercury could be melted with various metal into amalgam,
it is used in metallurgy to extract and purify metal, as patio process in gold or other rare metals
purification. Gold or silver amalgam turn hard rapidly, which is used as dental material usually.
Main used in refining gold.after screening by water,the granule left is different size grain,even
ash.The larger granule could be picked out,but many of which is too small to pick.It could be use
mercury to recover,because the mercury could absorb gold,when don’t take in fully,it still
fluid,then cover them with cloth,forcing out the redundant mercury,Amalgam is left.Distilling the
mercury by put the amalgam in stove.The finished gold contain silver usually.Then using other
method to dispart the gold and silver.
Mercury compound also have different uses. Mercury oxide as antifouling composition could be
used as oil paint for ocean ship bottom, depolarize in dry cell. Mercury bichloride used in tanning,
photograph and so on. Mercury sulfide is a kind of red coating used in rubber and printing ink.
