Product introduction:
High purity graphite crucible
details:
Graphite is the main raw material for crucible production, accounting for 45-55% of the ingredients, preferably crystalline flake graphite and needle (block) graphite. Flake medium carbon graphite is widely used in graphite crucibles produced in China, and the carbon content is generally 85-93%. The graphite particle size shall be selected according to the performance, use, model and specification of the crucible. Large scale graphite with 32 mesh or more is usually used for large crucibles with a volume of more than 100 #; 80 mesh flake graphite is used for the medium-sized crucible with a volume of 60 # ~ 80 #; Small crucibles with a volume of less than 50 # are made of 100 mesh flake graphite; The special shaped crucible for hand molding adopts - 100 mesh fine scale graphite.
