摘要： A highly heat-conductive aluminum nitride sintered body comprising 95.5 to 99.8% by weight of an aluminum nitride grain phase having an average grain size of 2 to 10 .mu.m and the rest being substantially a dysprosium oxide phase and having a density of at least 99% of the theoretical density, at least 30% by weight of the oxide phase existing at the triple points of the aluminum nitride grains. By forming an alumina-based oxide layer on the sintered body and further forming on the oxide layer a plating layer of Ni and/or Cu via a vapor deposition layer, there can be obtained a semiconductor substrate having a high bonding strength to solder.

摘要： A tough cermet made from 20-92 weight % of TiC and/or TiCN, 5-50 weight % of WC and 3-30 weight % of an iron-group metal. This tough cermet has a three phase grain microstructure consisting of a core phase rich in TiC and/or TiCN, an intermediate phase rich in WC and surrounding the core phase, and an outer phase made of (Ti,W)C and/or (Ti,W)CN and surrounding the intermediate phase. Because of this three-phase microstructure, the cermet has high toughness without sacrificing hardness. It is prepared by using WC powder of as fine as less than 3 .mu.m, without taking the course of forming a solid solution of TiC and/or TiCN and WC and pulverizing it.

摘要： This invention provides a method for producing an oxide superconductor which has a uniform texture and is markedly high in sintered density and current density.The method involves the formation of intermediate products from the starting materials. The intermediate products are then used to form the final product. Specifically, to form an oxide superconducting material having a compositional formulaYBa.sub.2 CU.sub.3 O.sub.7-8,where 8 is more than zero but less than 0.5, the method of the invention includes forming a first intermediate product of Y.sub.2 CU.sub.2 O.sub.5, forming a second intermediate product of BaCuO.sub.2, mixing the first and second intermediate products, and sintering the intermediate product mixture to form the oxide superconducting material.
