30/4/2009· In this work, silicon carbide ceramics were sintered by using Y 3 Al 5 O 12 as a sintering additive, and its mechanical properties were investigated. The sintering condition of hot-pressing is 1800 C, 2 h, vacuum atmosphere. The amounts of Y 3 Al 5 O 12 as a additives was 3, 5 and 7 wt%. as a additives was 3, 5 and 7 wt%.
Self-sintered silicon carbide carries a slight price premium compared to the reaction bonded version. Although the preferred seal face material, it often is too brittle for some seal face designs. It is one of the most popular materials used in mechanical seal face design and is recommended in high temperature water or hot oil appliions because of its excellent thermal conductivity.
