USE OF YTTRIA-MAGNESIA MIXTURES TO PRODUCE HIGHLY TRANSPARENT SINTERED ALUMINA BODIES

摘要

By using a combination of magnesia and yttria, or their precursors, in small amounts as sintering aids for alumina, sintered bodies having very high in-line transmission properties are produced. In addition the sintering time and/or temperature required to achieve a given inline transmission is reduced as compared with using only magnesia as a sintering aid.
