【摘要】 尖晶石族矿物广泛地分布于自然界,它们是许多变质岩和岩浆岩的主要矿物成分。工业上应用较多的主要是镁铝尖晶石和镁铬尖晶石。镁铝尖晶石耐火材料是目前冶金用耐火材料的重点发展方向之一,对这种材料的理论及应用研究也成为耐火材料研究的热点。尖晶石的其它应用,如尖晶石轴承及颜料等也取得了较大的发展。笔者根据尖晶石的矿物学特性,对尖晶石的生成以及工业生产的基本原理、基本工艺和基本过程作一系统的概述,并对尖晶石原料、含尖晶石工业制品的开发与应用作一简要的介绍。更多还原

【Abstract】 The spinel-group minerals are widely distributed in nature. They are important components of many metamorphic and ignious rocks. In this group, spinel (MgOAl2O3) and chromium spinel (MgO-Cr2O3) are the most important minerals applied in industry. This paper introduces the latest progress of some studies of mineralogical features of spinels. Some basic theories and principles of spinel formation and the basic technology and process of industrial production of spinel minerals are described. The development and application of raw minerals and products of spinels are also briefly introduced.更多还原
