Alumina is an electrically insulating material, with a high electrical resistivity, increasing with purity.Good chemical stability of alumina, leads to a high corrosion resistance. It is insoluble in water and only slightly soluble in strong acid and alkaline solution 1.Seal
Sintered Silicon Carbide ( SiC ) Properties and Appliions
Due to their greater resistance to both wear and thermal shock, sintered silicon carbide seal faces for automotive water pumps are replacing seal faces made of materials such as aluminium oxide. In many cases the material has proven more suitable in meeting the performance demands of U.S. and European vehicles – i.e. lasting the lifetime of the vehicle without leaking.

Silicon - Wikipedia
Silicon is a chemical element with the syol Si and atomic nuer 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor.It is a meer of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it. are below it.
Molecules and networks
Quartz (SiO 2) is an extended network of SiO 4 molecules, in which a central silicon atom is bonded to four oxygen atoms; each silicon atom has a half share of four oxygen atoms. Because of its “giant structure”, silicon dioxide is insoluble in water, and has a high melting and boiling point.

Silicon Dioxide in Food - Nutrineat
Silicon dioxide in food is very important for normal development of bones. Silicon dioxide, also referred to as silica, is necessary to maintain healthy skin, hair, and nails. Did You Know? Silicon (element) is found naturally in foods in the form of silicon dioxide (SiO 2).).
Wet-Chemical Etching and Cleaning of Silicon
Strong rinse in DI water is required after this cleaning step. Particle Removal: A Megasonic clean (at about 70 C) in a 5:1:1 ratio mixture of DI water: Ammonium Hydroxide : Hydrogen Peroxide will remove silica and silicon particles from the wafer, as well as remove certain organic and metal surface contamination. 2-10 minute clean is recommended.
Silicon nitride - Wikipedia
Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si 3N 4 is the most thermodynamically stable of the silicon nitrides. Hence, Si 3N 4 is the most commercially important of the silicon nitrides when referring to the term "silicon nitride". It is a white, high-melting-point solid that is relatively chemically inert
