Product Description

SiB6=92.95，density:3.0g/cm3，smelting point: 2200℃,Glossy black-gray powder, insoluble in water, resistant to oxidation, thermal shock, and chemical abrasion, especially with high strength and stability under thermal shock. It has excellent thermoelectric properties. It is used as a P-type high temperature thermoelectric material to replace boron carbide, and its hot end temperature can reach 1200°C. it can be used as engineering ceramic materials, sandblasting nozzles, blades of gas engines and other special-shaped sintered parts and seals.

Product Features

1.High purity: the highest purity can reach 99.99%, XRD detect no impurity phase, GDMS detect low metal impurity element content;

2.Concentrated distribution: standard normal particle size distribution, no bimodal or multimodal.
