Study on Color Change of Brown Sapphire in Changle, Shandong

Abstract:

Most Shandong sapphires color are indigo blue, green and brown yellow, these deep color influence their commercial value. This paper makes a comparative study of the traditional heat treatment and heat diffusion treatment on brown series of sapphire of Shandong. The results show that heat treatment is helpful to improve the transparency of Shandong sapphire, but cannot produce ideal color, and it also has no obvious effect on its internal features. However, diffusion treatments after adding TiO₂ can obtain comparatively ideal color, which is blue-green to blue. And the transparency and dark mineral inclusions are improved.
