<p>Dense ceramic composites comprising a mixture of a solid solution containing the elements Si, C, Al, O and N (referred to by the acronym SiCAlON) and a high temperature refractory phase have desirable physical properties and can be formed by pressureless sintering techniques. The refractory phase can be SiC, AlN, Al2O3,or AlON and constitutes between 1 and 99% of the volume of the ceramic. The method for pressureless sintering may also be used for densification of SiCAlON ceramics, or composites containing SiCAlON, allowing fabrication of the same into complex shapes economically.</p> |
