α型氧化铝性能与适用性关系研究

The Superficial Discussion for the Relation between Suitability and Applicability of α - Al_2O_3

通过对α型氧化铝制品干压密度、收缩率的检测过程数据的分析,阐述α型氧化铝煅烧温度与晶体大 小、晶体大小与易磨性、粉体颗粒级配与干压密度、干压密度与收缩率之间的相互关系,并讨论了以干压密度作为氧化 铝制品收缩率表征参数的可行性及适用性判断方面的经验。

According to analysis the data of the dry press density and the shrink rate of α - Al2O3 products, It' s expounded the relation between the calcination temperature of α - A1203 product and grain size, grain size and grinding, α - Al2O3 powder particle size distribution and the dry press density of green body, the dry press density of green body and shrink rate of product. Discussed the feasibility and experience judgment of using the dry press density value as the product shrink token parameter.
