    摘要: A sintered mullite-based body having an excellent dielectric constant and thermal expansion coefficient, and an improved flexural strength and surface smoothness, is obtained by heat treating a composition of 99.1 to 80% by weight of a mullite powder and 0.1 to 20% by weight of yttrium oxide as a sintering agent, optionally together with a colorant of MoO.sub.3.
