| 发明名称 | Ceramic compositions comprising alumina | ||
| 摘要 | A composition suitable for firing to obtain a ceramic material therefrom may include from about 1 to about 40 wt. % based on the total dry weight of the composition a first particulate material having a Mohs hardness of at least about 8.5 and a d50 of from about 7 μm to about 500 μm. The composition may include at least about 50 wt. % based on the total dry weight of the composition a second particulate material comprising alumina. The composition may include from 0 to about 10 wt. % based on the total dry weight of the composition a sintering aid. A green body or ceramic material may be formed from the composition. Ballistic armor may be formed from the composition or may include the ceramic material. | ||

| 主权项 | 1. A composition suitable for firing to form a ceramic material therefrom, said composition comprising: from about 1 to about 40 wt. % based on the total dry weight of the composition of a first particulate material having a Mohs hardness of at least about 8.5 and a d50 of from about 7 μm to about 500 μm, said first particulate material being fused corundum; at least about 50 wt. % based on the total dry weight of the composition of a second particulate material, said second material being calcined alumina other than fused corundum; and from 0 to about 10 wt. % based on the total dry weight of the composition of a sintering aid. | ||
