摘要：

The 1860°C isothermal section of the system Al4C3‐Be2C‐SiC was investigated on hot‐pressed samples. The equilibrium relations involve previously known phases SiC, Be2C, A14C3, Al,SiC4, and seven newly found compounds. On the binary Al4C3‐Be2C, three phases with molar ratios 3:1, 1:1, and 1:3 occur with large homogeneity ranges and deviations of stoichiometry. In the ternary, four phases with molar ratios Al4C3:Be2C:SiC of 4:1:1, 4:2:1, 4:2:2, and 8:1:4 occur. All newly found compounds show hexagonal symmetry with a∼0.33 nm and c ranging from 1.65 to 5.45 nm, except Al4C3=3Be2C, which is cubic with a= 0.4611 nm. Copyright © 1979, Wiley Blackwell.
