How are Gems Cut and Polished?
How are Gems Cut and Polished? Not required for EPS2 students The process of cutting and polishing gems is called gemcutting or lapidary, while a person who cuts and polishes gems is called a gemcutter or a lapidary (sometimes lapidarist). Gemstone material that has not been extensively cut and polished is referred to generally as rough.

A feasibility study of brazing silicon carbide to metals - TWI
Silicon carbide, and specifically sintered SiC, retains most of its strength to ~1500 C; in addition, it is a very hard material with good wear characteristics. These factors make it a candidate material for use in many aggressive environments; however it has a low CTE, ~4.5 x 10-6/°C.
It''s Elemental - The Element Silicon
Silicon forms other useful compounds. Silicon carbide (SiC) is nearly as hard as diamond and is used as an abrasive. Sodium silie (Na 2 SiO 3), also known as water glass, is used in the production of soaps, adhesives and as an egg preservative. Silicon 4
