Hexagonal boron nitride is a synthetic non-oxide ceramic material.Is a kind of white loose powder, similar to graphite properties, known as "white graphite".
Product features
● Our company's boron nitride powder introduced the international advanced technology production, to ensure the purity of the material and high temperature resistance;
● Boron nitride powder using cold isostatic pressing molding and bidirectional pressure hot pressing sintering process, the production of boron nitride powder caused by high density, long service life;
● Stable mature production technology and process, do not add any binder, to ensure the stability of boron nitride powder.
Typical applications
● Melting metal with high purity boron nitride crucible;
● A variety of resin system filling material;
● Sintering crucible, fire plate;
● High temperature furnace electrode insulation and protection tube;
● Boron nitride insulated components for polysilicon ingot furnaces.
