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
Alumina crucible is a type of aluminum oxide ceramic products. SAM provides alumina products with high purity, tight dimensional tolerance and competitive prices. Types of crucibles including E alumina crucibles and customized products are available.
Kurt J. Lesker Company | Silicon Si (P-type) Pieces …
Crucible liners will need to be replaced fairly often because liquid silicon has the tendency to damage liners. When silicon melts, it will mechanically bond to the inner walls of the crucible liner. Upon cooling or re-heating, the difference in thermal expansion/contraction of the silicon in contact with the liner can produce enough stress to break the liner.

Silicon Carbide (SiC): The Future of Power? | Arrow
Silicon carbide, also known as SiC, is a semiconductor base material that consists of pure silicon and pure carbon. You can dope SiC with nitrogen or phosphorus to form an n-type semiconductor or dope it with beryllium, boron, aluminum, or gallium to form a p-type semiconductor.
Graphite Crucible, Graphite Electrodes Factory
The crucible specifiion (size) is usually expressed by the size of the serial nuer. The crucible No. 1 has a volume that can melt 1000g of brass, and its weight is 180g. The melting amount of the crucible when smelting different metals or alloys can be calculated by multiplying the corresponding metal and alloy coefficient by the specific weight of the crucible.
