摘要： PURPOSE:To improve fracture toughness and strength by compressing and deforming a specified ceramic presintered body in one direction at a temp. where the presintered body can be plastic-deformed under pressure and expansion-deforming the body in the other direction. CONSTITUTION:Ceramics such as Si3N4, a sintering assistant, a solvent and a dispersant are mixed in a specified molar ratio to prepare argil. The argil is filled in the carbon die lined with a mold releasing agent of a hot press, cold-rolled under gaseous N2 pressure, then heated to a specified temp. and presintered to obtain a ceramic presintered body having a macrodome crystal or crystal nucleus. The presintered body is kept at high temp. and pressure, compression-deformed in the microdome crystal direction and then expansion- deformed in the orthogonal direction to form a two-dimensionally oriented secondary sintered body. The body is subjected to HIP to obtain a sintered body having >=8-9 MPam fracture toughness and >=1200-1300 MPa strength.

摘要： PROBLEM TO BE SOLVED: To provide a platinum paste capable of forming a conductor in which change of a film quality and conductivity caused by heating are hard to occur.
SOLUTION: In the platinum paste, because a crystallite size of platinum powder is sufficiently enlarged to be within a range of 60 to 100 (nm), sinterability is suppressed, and agglomeration is hard to occur even if exposed to a high temperature, and a resistance heating element layer in which change of the film quality and change of conductivity or a resistance value caused by heating are hard to occur can be formed.

摘要： PROBLEM TO BE SOLVED: To provide a highly heat-resistant platinum powder which does not cause inconvenience due to remaining alkali; a method for producing the platinum powder without using an inert gas; and a platinum paste suitable for a piezoelectric ceramic material. SOLUTION: The platinum powder includes a powder of an oxide of an elemental metal belonging to families 3 to 15, as an additive; and has a crystallite size sufficiently enlarged to 30 to 100 (nm) by heat treatment. The platinum paste for the piezoelectric ceramic material is produced by dispersing the powder in a vehicle. Thereby, the paste does not cause coagulation even when exposed to a high-temperature atmosphere, because the platinum particles are sufficiently inhibited from being sintered. Because the crystallite size is controlled to 100 (nm) or less, the platinum particles are sufficiently sintered in such an extent as a conductor is surely fixed to the surface on which the conductor is to be formed, and accordingly imparts sufficient electroconductivity to the formed conductor.

摘要翻译：要解决的问题：提供不会由于残留碱而引起不便的高耐热铂粉末; 不使用惰性气体制造铂粉末的方法; 以及适用于压电陶瓷材料的铂糊。解决方案：铂粉末包含属于3至15族的元素的氧化物粉末作为添加剂; 并且通过热处理使微晶尺寸充分地增大至30至100（nm）。用于压电陶瓷材料的铂糊料通过将粉末分散在车辆中来制备。因此，即使暴露在高温气氛下，由于铂粒子被充分抑制烧结，所以糊料也不会引起凝结。由于微晶尺寸控制在100（nm）以下，所以铂粒子被充分地烧结到导体固定在要形成导体的表面上的程度上，因此赋予形成的导体足够的导电性导体。版权所有（C）2007，JPO＆INPIT
