The quartz glass tubes are obtained through the use of different types of raw materials like natural or synthetic quartz sand after the process of smelting and fine grinding. Quartz glass tube contains no air bubble and is controlled to the grade of PPM, which resultant have ultra-high purity, good spectral transmission, well-controlled dimensions, and lower (OH) Hydroxyl.

• These are highly resistant to thermal shocks due to the extremely Low Coefficient of thermal expansion.

• These Quartz Tubes have excellent electrical strength that remains highly stable with temperature variation.

• Quartz glass has a series of excellent physical and chemical properties for electric fire barrels, electric baking stoves, electric heaters, and heating.

Advantage of Quartz Tube:

1. High purity , SiO2> 99.99%.

2. Working Temperature: 1250℃; Soften Temperature: 1730℃ .

3. Good thermal stability.

4. Acid-proof, Alkali-proof.

5. Excellent electrical insulator.

6. Transmission: Visible light >93%, UV light>85%.
