Calcium Hexaboride

Calcium hexaboride is black powder or particle, which is metal boride. It is insoluble in water. CaB6 would fire if heating to red in air, which oxidize into borate salt 1~2 hours. If heating in sulfur steam, CaB6 ignite and show bright red. Calcium metal piece and amorphous boron powder are the raw material.

Calcium boride uses as boron additive for  Baiyun carboniferous and magnesia dolomite refractory material, which take effects of antioxidant, anti-erosion and improving hot intensity.

CaB6 applies as deoxidizing degrassing agent to  increasing electric conductivity and strength of red copper. It is also a new material in shielding neutron in nuclear industry.

Calcium boride powder is new semiconductor material for spin electronic components at Curie point 900K.  It is also raw material for production of boron trichloride (BCl3) and amorphous boron.

CaB6 particle is raw material for production of high purity metal borides (as TiB2, ZrB2, HfB2 and so on) and high pure boron alloys (Ni-B, Co-B, Cu-B and so on).

CaB6 powder uses to make mixture of catalyzer Ca-B nitride (Ca3N2N4) and hexagonal boron nitride.

Calcium boride granule uses as desulfurizing deoxidizing boron-adding agent of boron alloy or boron steel casting .

Calcium hexaboride applies as desoxidant of metal melting.
