Thermal stability of MoSi2-TiB2-CrB2 composites at 900–1400°C

Slip casting procedure with subsequent firing in air is used to synthesize composites (100 − x)MoSi2−xMB2, where M = Ti, Cr, (Ti, Cr) and x = 10, 20, and 30 mol % at 900–1400°C. The MoSi2-CrB2 and MoSi2-(Ti, Cr)B2 composites containing 20 and 30 mol % of borides are found to possess the highest protective properties. The optimum temperature range for sintering is 1100–1400°C.
