摘要： A SiAlON armor ceramic made from a starting powder mixture including silicon nitride powder. The armor ceramic includes a ceramic body that has between about 64 weight percent and about 90 weight percent alpha SiAlON phase that contains an alpha SiAlON-bound rare earth element. The ceramic body also has between about 5 weight percent and about 35 weight percent of a beta SiAlON phase of the formula Si6−zAlzOzN8−z wherein the value of “z” ranges between about 0.10 and about 0.35. The alpha SiAlON-bound rare earth element in the alpha SiAlON phase is present as a result of the starting powder mixture that contains between about 1 weight percent and about 7 weight percent of an oxide of the alpha SiAlON-bound rare earth element. The ceramic body has a fracture toughness (KIC) greater than about 6.00 MPa·m1/2 and a Vickers hardness (HVN) equal to greater than about 19.3 GPa.

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.
