Superior finished Quartz Disc, Plates & Flanges

Quartz Plates.png

Quartz plate/sheet usually smelted and cut by quartz, they have a silica content of over 99.99%. The hardness is seven grades of Mohs, and it has the characteristics of high-temperature resistance, low thermal expansion coefficient, thermal shock resistance, and good electrical insulation performance.


The Quartz glass plate/sheet can be customized at the customer's request.


Available Size:


Square Quartz Glass Plate/Sheet: 

Length     -     5mm-1500mm

Round Quartz Glass Plate/Sheet:

Diameter  -    5mm-1500mm

Thickness -    0.5mm-100mm

We Can Do:

  1. Different raw materials for different applications for customers to choose.

JGS1 (Far Ultraviolet Optic Quartz slab)    

JGS2 (Ultraviolet Optic Quartz slab)  

JGS 3 (Infrared Optic Quartz slab)

2. Strict size and tolerance control.

3. No air bubble, no airline.

4. Professional inspection before delivery.

Advantage of Quartz Glass Plate/Sheet:

1. Resistance to high temperature.

2. Good chemical stability, acid-proof, alkali-proof.

3. Lower coefficient of thermal expansion.

4. High transmittance

Quartz Flanges are designed in such a manner that will fix two endpoints of the tube. These flanges can be available in Milky and Translucent Form. Quartz flange is used in experiments, chemical analysis, tests, etc. due to its following properties-

  1. High-temperature resistance glass can work under 1250°C continuously, and in short, time can even work under 1450°C, its softening point is 1730°C.

  2. Quartz glass will not react chemically with acid except hydrofluoric. 

  3. Electric insulation.

  4. Excellent thermal shock stability

  5. High transmission above 85%


Transparent Quartz Plates and Flange are widely used in electric light sources, electrical appliances (electric), semiconductors, Solar, optical communications, military industry, metallurgy, building materials, chemical, machinery, lighting, electricity, environment-protection, and others.
