Refractories Aims and scope

Conclusions

A technique for the reaction sintering of a new refractory made of 82–83% boron nitride and 17–18% graphite has been developed.

The refractory possesses high specific resistance up to 1500–1800°, a low coefficient of thermal expansion, a moderative evaporation rate in a vacuum, satisfactory strength and machinability, as well as high resistance to cryolite-aluminum melts, borate, chloride and also silicide and boron-silicon alloy melts (at between 900 and 2000°).
