Features and advantagesAdopt international advanced technology high-temperature boron nitride raw materials to ensure material purity and high-temperature resistance.
Using cold isostatic pressing and two-way pressure hot pressing sintering process, the material has high density and long service life.
Stable and mature production technology and process, without adding any binder, to ensure material stability.
Applications:1.High-purity boron nitride crucible for molten metal.
2.Nitride phosphors, silicon nitride, aluminum nitride and other ceramics and powder sintering crucibles, setter plates.
3.High temperature furnace electrode insulation and protection tube.
4.Boron nitride insulation components for polysilicon ingot furnaces.
