熱水反応により造られる人工水晶

抄録

This paper is concerned with the synthesis of quartz crystal by hydrothermal reaction. The mechanism and control of the crystal growth, and how to evaluate the quality of the synthetic quartz crystal are discussed, as well as the brief historical review of synthetic quartz production. To manufacture synthetic quartz crystal, developers employ the hydrothermal temperature gradientmethod. This manufacturing process remains unchanged from the early days of synthetic quartz crystal development and manufacturers will continue to use it in the future. Since industries began massproducing of synthetic quartz crystal, makers have developed quartz crystal products to meetchanging market demands, including the demand for optical parts. As the demand for quartz resonators continues to expand, users will issue more exacting requirements about size, precision and stability. Makers will have to escalate their quality control and growth control procedures.
