PRODUCT INQUIRY

Quartz rod is a special industrial glass rod, which has excellent physical and chemical properties:

High temperature resistance: quartz glass rod softening point is 1730 degrees, it can be used at 1100 degrees for a long time, short time high temperature can reach 1400 degrees.

Corrosion resistance: Except hydrofluoric acid, quartz rods almost don’t react with all other acids. Its high temperature chemical stability is incomparable to other materials.

Good thermal stability: quartz rod has a good coefficient of thermal expansion, it can withstand drastic temperature changes, when it is heated to 1100 degrees, and then put in room temperature water, it will not crack.

Good transmittance: Quartz rod has good transmittance in ultraviolet and infrared bands, visible light transmittance is greater than 95%, UV spectral region, transmittance is greater than 90%.

Good electrical insulation: the resistance value of quartz rod is almost ten thousand times that of ordinary glass rod, it is an excellent electrical insulation material.

Quartz rods are widely used in electric light source, optical communication, chemical industry, semiconductor, machinery, electric power, building materials, military and other fields
