HIGH TEMPERATURE LOW THERMAL EXPANSION CERAMIC |
摘要 |
This invention relates to the high temperature stabilization of aluminum titanate and aluminum titanate-mullite compositions by the addition of iron oxide. It has been found that iron oxide concentrations greater than 5 weight percent and as high as approximately 25 weight percent have a stabilization effect at high temperatures on aluminum titanates. The resultant ceramic body is further enhanced by the addition of from .1 to 5 weight percent rare earth oxide. |
