Refractory and high-temperature materials are hard, heat-resistant products such as alumina cement, fire clay, bricks, precast shapes, cement or monolithics, and ceramic kiln furniture. Ceramic refractories have high melting points and are suitable for appliions requiring wear-resistance, high temperature strength, electrical or thermal insulation, or other specialized characteristics.

Silicon carbide whiskers have excellent mechanical and chemical properties, making them very desirable as a reinforcement for structural ceramic and other composite materials. Los Alamos has developed a laboratory-scale batch process for producing very high quality SiC whiskers by the vapor-liquid-solid (VLS) method which is an active candidate for technology transfer involving significant …

In a subsequent stage the resulting glassy moldings are converted into crystalline α-silicon carbide at from 1950 to 2200 C. Compact pore-free silicon carbide moldings are produced by compressing amorphous silicon carbide powder in the absence of sintering assistants at from 1400° to 1800° C. and under from 100 to 2000 kp/cm 2 to give dense, glassy moldings.
A composite material that increases in temperature upon exposure to electromagnetic radiation comprising single crystal silicon carbide whiskers and fibrils in a matrix material. Also, heat-generating objects comprising the composite material, and a method of generating heat.

There are nearly 3,000 FRCI tiles on the shuttle, primarily in areas of high heat. FRCI tiles are mostly used on the base of the shuttle; this is where the highest heat is encountered. 4. Low-Temperature Reusable Surface Insulation (LRSI) white tiles are used in
Over half of the companies are loed either in the United States of America (primarily in California) and in Europe (primarily in Spain). Within CPV, there is a differentiation according to the concentration factors (high concentration >300 suns (HCPV), medium concentration 5 < x < 300 suns (MCPV), low concentration <5 suns (LCPV)) and whether the system uses a dish (dish CPV) or lenses (lens CPV).

2014/6/6· Commercial production of RCFs began in the 1950s in the United States, and production increased dramatically in the 1970s. Domestic production of RCFs in 1997 totaled approximately 107.7 million lb. Currently, total U.S. production has been estimated at 80 million lb per year, which constitutes 1% to 2% of SVFs produced worldwide.
