[Technical Information] About Quartz, Silica, Siliceous Rock, Crystal, and Silica Sand
We are currently offering technical materials that deepen your knowledge of 'silica,' which has high heat resistance of over 1000°C and excellent chemical resistance!
Nitchitsu Co., Ltd., which provides "high silica" (refined silica powder, etc.) to a wide range of industrial fields, has prepared a technical document explaining the classification and characteristics of silica, as well as the features of quartz. Additionally, we introduce examples of applications such as "fused quartz glass" and "synthetic quartz glass" produced by melting quartz powder. ■ Characteristics of Silica - High heat resistance. It can withstand high temperatures of over 1000°C! - High chemical resistance. It slightly dissolves in acids and alkalis, but the rate of dissolution is extremely low. ■ Applications For semiconductor industry, LCDs, optical fibers, optics, scientific research, mercury lamps, sterilization lamps, infrared lamps, optical fibers, semiconductor purification containers, crucibles for pulling silicon single crystals, and more... *For more details, please refer to the PDF document or feel free to contact us.

Company information
Silica is one of the most familiar and abundant materials used in various applications such as ceramics. Today, it is utilized in electronic devices, including semiconductors and liquid crystals, making it an essential material that supports our highly developed modern civilization. The High Silica Business Division provides "High Silica" (refined silica powder, etc.) to a wide range of industrial sectors. "High Silica," obtained by refining silica and quartz, is a high-purity product with a purity of 99.6% to 99.9%, created through advanced grinding, classification, and chemical processing technologies developed through active technological innovation. It is used in cutting-edge fields of the IT-related industry, such as quartz crucibles, quartz glass, special glass, high-purity optical lenses, CCD cover glass, and semiconductor-related fillers. Furthermore, by applying the manufacturing technology of "High Silica," we have established robust production facilities and a strict quality control system to meet the increasingly sophisticated needs of our customers.
