Crucible steel - Wikipedia

Crucible steel is steel made by melting pig iron (), iron, and sometimes steel, often along with sand, glass, ashes, and other fluxes, in a crucible. In ancient times steel and iron were impossible to melt using charcoal or coal fires, which could not produce temperatures high enough.

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[4] when referring to the term "silicon nitride". It is a white, high-melting-point solid that is relatively chemically inert

Silicon Carbide (SiC): Properties and appliions | …

Silicon carbide has been the most widely used material for the use of structural ceramics. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a wide range of uses.
