A composition containing MgAl2O4, SiC, and B4C is produced by the method comprising: (a) combining sources of magnesium silicate, B2O3, Al and C to form a mixture, and (b) heating the mixture whereby the sources react to form MgAl2O4, SiC, and B4C. A sintered material containing MgAl2O4, SiC, and B4C, may be produced by the method comprising: (a) combining sources of magnesium silicate, B2O3, Al and C to form a mixture, (b) compacting the mixture into a shape, (c) heating the shape, whereby the sources react to form MgAl2O4, SiC, and B4C, and (d) sintering the reacted shape. Possible sources of magnesium silicate are talc, vermiculite and mica. |
