摘要
在黑龙江红蓝宝石物理性质、光学性质和化学成分研究基础上 ,对红蓝宝石致色因素进行了初步探讨 ,认为黑龙江红蓝宝石按颜色可以划分为红色、蓝色两个系列共 12种颜色 ,其物理性质、光学性质和化学成分具有明显区别。波谱分析表明 ,红色宝石的颜色由铬、镍、铁致色元素引起 ,蓝色宝石的颜色由铁、钛致色元素引起 ,其颜色浓淡和色调变化的主要原因在于铁的含量和Fe3 + /Fe2 +
Based on a study of physical and optical properties and chemical contents of ruby and sapphire from Heilongjiang Province, together with a preliminary discussion on the color_causing factors of these two minerals, it is believed that ruby and sapphire in Heilongjiang Province can be divided into red and blue series consisting totally of twelve colors. Their physical and optical properties and chemical contents show remarkable differences. Spectral analysis shows that the color of ruby is caused by the color_causing elements nickel, chromium and iron, whereas the color of sapphire by the color_causing elements iron and titanium. The variations of their color shading and tone result mainly from the iron content and Fe^(3+)/Fe^(2+) ratio.
