摘要： The flexural strength and stress rupture life of isostatically hot pressed silicon nitride containing between 1 and 12 weight percent of rare earth oxide and not more than 0.5 weight percent alumina is substantially increased by treating green bodies in flowing nitrogen at a temperature between 1000.degree. and 1500.degree. C. before degassing for the isostatic hot pressing. The iron content of the bodies is also reduced by this heat treatment, and this is believed to eliminate sources of fracture failure. Silicon nitride bodies with a flexural strength in excess of 525 MPa at 1370.degree. C. and with stress rupture lives reliably in excess of 200 hours at 300 MPa stress at 1370.degree. C. can be prepared in this way. The strain rates of silicon nitride under high temperature stress can also be reduced.

摘要： A dual phase silicon aluminum oxynitride material comprising a first phase Si-Al-O-N, commonly referred to as .beta.-Si-Al-O-N, and a second phase Si-Al-O-N referred to as .alpha.-Si-Al-O-N. In addition to the double phase Si-Al-O-Ns, there is included a glassy type material which can formulate up to ten percent by weight of the total composition. The material may be manufactured by forming a polytype material made from reacted alumina, aluminum nitride and silicon nitride. The polytype material may be mixed with further powders of silicon nitride and an oxide of yttrium, lithium or calcium and finally reacted to a double phase Si-Al-O-N material where hardness is increased as the additional .alpha.-Si-Al-O-N is increased without significantly affecting its strength.The material may be formed in situ by mixing aluminum nitride, alumina, silicon nitride, together with an oxide of yttrium, lithium or calcium. These materials can then be sintered to a final product containing a double phase Si-Al-O-N. Control of the alumina content in the polytype or in situ methods affects the percentage of .alpha.-Si-Al-O-N produced in the final product. The hardness of the material increases with the .alpha.-Si-Al-O-N content without significantly affecting its transverse rupture strength.
