High Purity Quartz Tube for High Temperature Tube Furnace

Quartz Tube

Introduction of Quartz Tube:

Quartz tube is a special industrial technical glass made of silica, which is a very good basic material. It is usually used in a tubular electric furnace with a heating temperature below 1200°C.
Quartz tubes can be divided into “qualified tubes” → “primary tubes” → “superior tubes” → “dehydroxylation tubes” according to different performances. The quartz tubes sold by our company are the highest grade dehydroxylation tubes, and the service life and temperature resistance are the best among all quartz tubes.

Application:

ZYLAB High purity quartz tube special for tube furnaces.

Main Features:

1. High temperature resistance.
The softening point temperature of quartz glass is about 1730°C. Most manufacturers provide excellent-grade quartz tubes that can be used for a long time at 1100°C. Our quartz tubes not only can be used for a long time at 1150°C, but also can be used for a short time (within 5h) at 1200℃.
2.Corrosion resistance.
Except for hydrofluoric acid, the dehydroxylated quartz tube hardly chemically reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. Especially its chemical stability at high temperatures is any other engineering materials that are incomparable.
3.Resistant to rapid cold and heat, long service time.
The thermal expansion coefficient of the dehydroxylated quartz tube we produce is extremely small and can withstand drastic temperature changes. The quartz glass is heated to about 1200°C and will not burst when placed in normal temperature water.
