Aluminum Oxide is a white, odorless, crystalline (sand-like) powder. It is used in abrasive and refractory materials, ceramics, laboratory-ware and paper, and as an adsorbent for gases. Hazard Rating Key: 0=minimal; 1=slight; 2=moderate; 3=serious; is on

Aluminium production process

ALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.

Silicon Wafer Manufacturing Process - Silicon Valley …

The stock removal process removes a very thin layer of silicon and is necessary to produce a wafer surface that is damage-free. On the other hand, the final polish does not remove any material. During the stock removal process, a haze forms on the surface of the wafer, so an extra polishing step gives the wafer a mirror finish.

Corrosion characteristics of silicon carbide and silicon nitride

current view of the corrosion of silicon carbide quite well. For silicon nitride, the oxide scale is ac- tually a double or duplex layer in which an inter- mediate phase of silicon oxynitride occurs between the outer silica scale and the silicon nitride sub- strate [14
