摘要： The present invention is to produce an aluminum nitride powder which is turned into a sintered body at a temperature of not more than 1600° C., thereby obtaining a sintered aluminum nitride in which the density and thermal conductivity are high and which can be properly used as a substrate material.Using a vapor phase reaction apparatus shown in FIG. 1, ammonia gas was fed from a reactor 2 heated at from 300 to 500° C. and maintained at that temperature by a heating section 1 via a feeding tube 4 while being regulated by a flow regulator 3. At the same time, while being regulated by the flow regulator 5, nitrogen gas containing an organic aluminum compound is fed via a feeding tube 6 to obtain an aluminum nitride powder. The aluminum nitride powder is subjected to a heat treatment at from 1100 to 1500° C. in a reducing gas atmosphere and/or an inert gas atmosphere to obtain an aggregate aluminum nitride powder. The aggregate aluminum nitride powder is subjected to a mechanical treatment to obtain an aluminum nitride powder in which the specific surface area value is not less than 30 m2/g and a ratio of an average particle diameter to a particle diameter in terms of the specific surface area is not more than 10.

It is substantially free of Pb, hence suited for use as a steel friendly to the global environment. [Ca]e is the effective Ca concentration index (ppm by mass), T.[Ca] and T.[O] are the contents of Ca and O, respectively, in ppm by mass, and (O)ox and (Ca)ox are the proportions of O and Ca contained in oxide inclusion, respectively.
摘要翻译： 1.一种机械结构用钢，其以质量％计含有C：0.1〜0.6％，Si：0.01〜2.0％，Mn：0.2〜2.0％，S：0.005〜0.20％，P：0.1以下％，Ca：0.0001〜0.01％，N：0.001〜0.02％，Al：不大于0.1％，余量为Fe和杂质，[Ca] e = T定义的[Ca] e值。 Ca] - （T. [O] /（O）ox）x（Ca）ox不大于5ppm或氧化物夹杂物中所含的MnO比例不大于0.05，Ca / O值不为 0.8以上的机械加工性优异，因此可以用作各种机械结构钢部件的钢坯，如工业机械，工程机械，汽车等输送机械。它基本上不含Pb，因此适合用作对全球环境友好的钢铁。 [Ca] e是有效Ca浓度指数（质量ppm），T. [Ca]和T. [O]分别为质量ppm和（O）ox和（Ca ）ox分别是氧化物夹杂物中含有的O和Ca的比例。
