MARUWA uses imported and domestic fused quartz glass bars, tubes, and sheets as raw materials for manufacturing. The ideal type for the demanded product characteristics is selected in view of quality from among several types of raw materials according to the difference of production processes. The Part No. and representative applications of our products, as well as the example of analysis of ingredients, are shown below.

Raw
materials

Oxyhydrogen fusion method

This quartz glass is made by the oxyhydrogen fusion method using stringently selected high-purity quartz powder. The OH radial contained in the glass prevents diffusion of impurities, which produces an excellent effect especially when a diffusion process is used in the semiconductor production process. Furthermore, the quality is stable, hardly causing coloring due to radioactive rays.

Electric melting method

This quartz glass is made by the electric melting method using stringently selected high-purity quartz powder. Since the heat resistance is superior to that of the oxyhydrogen fusion quartz glass, it produces an excellent effect in processes in a high-temperature zone. Furthermore, there is no infrared absorption when the wavelength is 2.7mm.

Synthetic quartz

This is synthetic quartz glass made from a high-purity synthetic quartz materials. Since it produces an excellent effect in optical systems, it is used for cells for spectrophotometers.
