Research on Synthetic Quartz Crystal Quality

Abstract:

The quality of two synthetic quartz crystals, Z lump and Y bar, was researched by the infrared spectrophotometer technology and chemical spectral analysis in this study. The relationships between typical impurity OH and other impurities such as Fe, CO and Mg were discussed which impacted the quality of artificial rock crystal; the defects in artificial rock crystal and crystals, such as lattice dislocation and distortion with a close relation appear at the same time and impact the quality of synthetic quartz. The work in future should begin from the following two aspects in order to improve synthetic quartz crystal quality: the one is to further study the crystal structure characteristics and to explore the cutting type of crystal with convenient cultivation and processing process, high use ratio and high Q value. For example, the research is to make the Z area of Y bar crystals bigger and the other areas smaller or disappear. The other one is to improve the existing technological level and to reduce defects.
