Honglei New Material

Quartz Ring is a special industrial technical glass made of silica dioxide (SiO2), and quartz rings produced by manufacturers of high-purity quartz sand are excellent basic materials. Quartz rings possess a range of excellent physical and chemical properties, including:

1. High-temperature resistance: The softening point temperature of quartz glass is approximately 1730°C, allowing for prolonged use at 1100°C and short-term usage at temperatures up to 1450°C.

２. Corrosion resistance: Quartz glass, except for hydrofluoric acid, is virtually inert to other acidic substances. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Particularly, its chemical stability at high temperatures is unmatched by any other engineering material.

３. Good thermal stability: Quartz glass has an extremely low coefficient of thermal expansion, enabling it to withstand drastic temperature changes. Heating quartz glass to around 1100°C and then placing it in room temperature water will not cause it to crack.

４. Excellent optical transparency: Quartz rings exhibit excellent transparency across the entire spectrum from ultraviolet to infrared. The visible light transmittance is above 93%, and in the ultraviolet range, it can reach over 80%.

 The formation of quartz rings is a result of the high viscosity of their molten state. They are widely used in various industries, including semiconductor manufacturing, electro-optical sources, semiconductor communication devices, lasers, optical instruments, laboratory equipment, electrical equipment, medical devices, high-temperature and corrosion-resistant chemical instruments, chemical industry, electronics, metallurgy, building materials, defense, and more. Quartz rings produced by quartz testing manufacturers have high precision, no bubbles, smooth and flat surfaces, corrosion resistance, and excellent transparency, making them particularly suitable for the fields of optics, electronics, chemical industry, and defense.
