Latest Patents

Yabuta's latest patents include a "High strength high oxidation-resistance sialon sintered body." This invention describes a ceramic material that comprises a double phase complex sialon sintered body of .beta.'-type sialon and O'-type sialon. The material is composed of the four elements of silicon, aluminum, oxygen, and nitrogen, with a weight ratio of .beta.'-type sialon to O'-type sialon ranging from 7/1 to 3/5. The resulting .beta.'-phase-O'-phase complex sialon exhibits a dense structure, providing excellent high strength and high oxidation resistance.

Another significant patent is the "Method for molding of powders." This invention focuses on the method of compression molding metallic or ceramic powders. The process involves maintaining a negative pressure within a first mold of noncompactable powders, which allows for intimate contact with a pouch-like member made of thin-walled resilient material. This method produces a second mold, into which starting powders are compactly charged while air is exhausted and sealed. The pre-molded body of the metallic or ceramic powders is then processed using a cold or hot isostatic press.
