五彩金星玻璃晶相的研究

A Study on Crystal Phase in Multi-colored Aventurine Glass

一般金星玻璃中的片状晶体呈单色,或为金黄色,或为银白色,或为绿色等。而本研究制成的金星玻璃中所悬浮的片状晶体则是多色彩的,有宝石蓝、宝石红、玫瑰紫、桔红、赤金、柠檬金黄等色。在光照下,五彩缤纷,故称之为“五彩金星玻璃”。它是由化工铬渣、高炉渣和一般玻璃原料配制而成的。

The mnlti-colored aventurine glass is made from chromium slag, blast furnace slag, as well as normal raw materials for glass.The multi-colored flake crystals flash in dark green glass matrix.The crystal phases have been separated from glass by physical and chemical methods and have been studied by means of optical microscopy and X-ray diffraction. In this glass,cry-stal phases are eskolaite and chromite. Eskolaite is primary crystalline phase and presents various colours.
