Cotter, P G; Potter, R A

A method for making a self-bonding ZrB/sub 2/ abrasive and refractory material is patented. A mixture of zirconium silicate (zircon) particles, boron carbide (or boron carbide and boron oxide), and carbon are reacted in a C crucible under vacuum or an inent atmosphere at temperatures from ontrol migra- 1350 c- C to ontrol migra- 1900 c- C. The reaction product is removed fromtthe crucible, screened to remove any C present, and placed in a graphite die, where it is subjected to heat and pressure to obtain the desired material. (M.P.G.)
