Nanoscale Silicon Carbide Particles are typically 10 - 150 nanometers (nm) with specific surface area (SSA) in the 10 - 75 m 2 /g range. Nano Silicon Carbide Particles are also available in ultra high purity and high purity and coated and dispersed forms. They are also available as a dispersion through the AE Nanofluid production group.

Production of SiC whiskers - Great Lakes Carbon Corporation

Aug 11, 1981· β-Silicon carbide whiskers are produced in good yield from rice hulls. The hulls are ashed in air to obtain a yield of approximately 20% of amorphous silica on the raw material, which is in a favorable form for the production of SiC whiskers.

Crystal detector - Wikipedia

Silicon detector. Patented and first manufactured in 1906 by Pickard, this was the first type of crystal detector to be commercially produced. Silicon required more pressure than the whisker contact, although not as much as carborundum. A flat piece of silicon was eedded in fusible alloy in a metal cup, and a metal point, usually brass or gold, was pressed against it with a spring.
