湖北英山刚玉矿床是本世纪五、六十年代发现的,由于多种原因未能对其进行研究和开发利用。本文系统地研究了英山刚玉矿物学特征,测定了各种物性和参数,观测了刚玉包裹体;并利用电子探针、粉晶X射线分析、可见光谱等现代测试手段,较详细地分析了刚玉的化学成分、晶体结构及光谱特征,并进行了热处理实验研究。指出湖北英山产出的刚玉颗粒大,晶形好,颜色较浅,可用热处理的方法改成蓝色、黄色、肉红色,但由于裂隙发育,包裹体密集,透明度差,能达到宝石级的极少,若提高宝石级产量,必须进一步解决裂隙拟合的工艺研究。
The Yingshan corundum deposit in Hubei Province was discovered in the 1950s and 1960s and has not been researched, developed and utilized for many reasons. In this paper, we systematically studied the mineralogical characteristics of Yingshan corundum, measured various physical properties and parameters, and observed corundum inclusions. By means of modern testing methods such as electron probe, powder X-ray analysis and visible spectrum, we analyzed in more detail Corundum chemical composition, crystal structure and spectral characteristics, and conducted heat treatment experimental study. The results show that the grains of corundum produced by Yingshan in Hubei Province are large, the crystal form is good and the color is shallow. The method can be changed into blue, yellow and flesh red by heat treatment. However, due to the development of fissures, the inclusions are dense and the transparency is poor, Less, if you increase the gem-level production, we must further solve the fissure fitting process.
