Natural zeolites occur in over 40 countries and are mined in 11 of these at a rate of around 250 thousand tonnes per year. Discovery of the characteristic ion-exchange, dehydration and selective-adsorption properties of these zeolites, which are related to their unique honeyco structure, stimulated the development of several processes for the manufacture of synthetic zeolites. These

The aim was to manufacture high‐quality polycrystalline silicon films with a thicknesses up to 40 μm. The experiments focused on nucleation and growth of silicon on ceramics. Our research has shown that the deposition of a silicon layer on ceramic substrates cannot be compared with the well‐known growth mechanism of silicon on amorphous substrates like .

Commercially it can be made by the hy- drolysis of calcium carbide, by thermal cracking or partial coustion of natural gas. The acetylene obtained from the calcium carbide pro- cess, the most usual method of manufacture, has a garlic-like odor due to contamination by phosphine, hydrogen sulfide, and ammonia produced from calcium carbide impurities.

Black Silicon carbide grain Henan,China

Black Silicon carbide is an extreme hard carborundum, it is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke. Silicon Carbide is produced by a process involving the electrochemical reaction of silica(SiO2) – in the form of quartz mixed with Carbon(C) in the form of raw petroleum coke.

Silica is eliminated progressively as metakaolin transforms to the spinel phase and thence to mullite. The X‐ray data show variation in the mullite parameters between 1200° and 1400°C.; at 1400°C., the composition probably approximates 3A1 2 O 3 ·2SiO 2 .
