    Ceramic capacitors: Ceramic Class 1 capacitors: paraelectric ceramic mixture of Titanium dioxide modified by additives: Predictable linear and low capacitance change with operating temperature. Excellent high frequency characteristics with low losses. For temperature compensation in resonant circuit application. Available in voltages up to 15,000 V

  3. Cemented carbide - Wikipedia

    en.wikipedia.org/wiki/Cemented_carbide

    The coefficient of thermal expansion of cemented tungsten carbide is found to vary with the amount of cobalt used as a metal binder. For 5.9% cobalt samples, a coefficient of 4.4 μm/m·K was measured, whereas 13% cobalt samples have a coefficient of around 5.0 μm/m·K.

  4. Ceramic armor - Wikipedia

    en.wikipedia.org/wiki/Ceramic_armor

    Ceramic armor is armor used by armored vehicles and in personal armor to resist projectile penetration through its high hardness and compressive strength. In its most basic form, it consists of two primary components: A ceramic layer on the outer surface, called the "strike face," backed up by a ductile fiber reinforced plastic composite or metal layer.

  5. Powder metallurgy - Wikipedia

    en.wikipedia.org/wiki/Powder_metallurgy

    Iron powder is commonly used for sintering. Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powders.PM processes are sometimes used to reduce or eliminate the need for subtractive processes in manufacturing, lowering material losses and reducing the cost of the final product. [1]

  6. Ilmenite - Wikipedia

    en.wikipedia.org/wiki/Ilmenite

    Ilmenite is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. Ilmenite is the most important ore of titanium [5] and the main source of titanium dioxide, which is used in paints, printing inks, [6] fabrics, plastics, paper, sunscreen, food and cosmetics.

  7. Barium titanate - Wikipedia

    en.wikipedia.org/wiki/Barium_titanate

    Barium titanate is a dielectric ceramic used in capacitors, with dielectric constant values as high as 7,000. Over a narrow temperature range, values as high as 15,000 are possible; most common ceramic and polymer materials are less than 10, while others, such as titanium dioxide (TiO 2), have values between 20 and 70. [11]

  8. Titanium powder - Wikipedia

    en.wikipedia.org/wiki/Titanium_powder

    The powders produced are spherical; between 100 and 300 μm is size, with good packing and flow characteristics, making the powder ideal for high quality, near net shapes produced by HIP, such as aviation parts and porous coatings on hip prostheses. In the titanium gas atomisation (TGA) process, titanium is vacuum induction skull melted in a ...

  9. Hip prosthesis zones - Wikipedia

    en.wikipedia.org/wiki/Hip_prosthesis_zones

    Zones of a hip prosthesis, by the DeLee and Charnley system, [1] and the Gruen system. [2] After hip replacement, hip prosthesis zones are regions in the interface between prosthesis material and the surrounding bone. These are used as reference regions when describing for example complications including hip prosthesis loosening on medical imaging.
