雄黄与光反应的研究进展
Progress in the Study of Light Induced Alteration of Realgar
摘要
Abstract
In recent years mineral crystals have been collected by more and more people in China.Because of its vibrant color,brilliant natural luster and incredible sculptural qualities,realgar crystal is popular for geological museums and private mineral collectors.However,when exposed to sunlight,unprotected realgar develops a surface coating of friable yellow material.Due to their photochemical sensitivity,arsenic chaleogenides are important materials for use in optics.A lot of research work on light induced alteration of realgar was carried out in foreign countries.Reaction products of realgar and light are pararealgar,arsenolite and x-phase.Realgar is indirectly transformed into pararealgar via the As4S5 molecule.Realgar is a kind of Chinese traditional medicine,but the AS2O3 in realgar is toxic.The content ofAs2O3 in realgar is related to such factors as high temperature and light.A lot of research work on composition of realgar as Chinese traditional medicine has been carried out,but the study of light induced alteration of realgar should be strengthened in China.关键词
