摘要：

A silicon nitride ceramic is prepared by a modified sintering of reaction bonded silicon nitride method (SRBSN). This ceramic has a very high thermal conductivity, high fracture toughness, and a high strength. It is expected to be used as the next-generation insulating substrate material for high-power electronic devices and other new applications.
