摘要：
A ceramic body (20), as well as a hot-pressing method or a sintering to full density method of making the ceramic body (20). The hot-pressed ceramic body (20) contains between about 15 and about 35 volume percent of a boron carbide phase, and at least about 50 volume percent of alumina. The sintered to full density ceramic body (20) contains between about 15 and about 50 volume percent of a boron carbide phase and at least about 50 volume percent alumina. The substrate (21) further includes at least one of the following components (a) through (b) wherein the sum of the amounts of components (a) and (b) is equal to an effective amount to achieve full densification wherein components (a) and (b) include (a) a metal component including one or more of aluminum, magnesium and zinc; and (b) a reduction component containing carbon.
