transparent quartz glass square tube

Quartz glass square tubes are special industrial glasses. Manufacturers make them from high-purity silicon dioxide. They have excellent physical and chemical properties. So, they are key materials in many fields.

Characteristics

Their softening point temperature is about 1730℃. You can use them at 1100℃ for long periods and at 1450℃ for short times. This high-temperature resistance lets quartz glass square tubes excel in hot environments. Also, quartz glass, except for hydrofluoric acid, has high acid resistance. It is 30 times more resistant than ceramics and 150 times more than stainless steel. No other substance matches its chemical stability at high temperatures.

Quartz glass can withstand drastic temperature changes. It has a very low thermal expansion rate. Even if you heat a quartz glass square tube to around 1100℃ and then quickly place it in cold water, it will not crack. Also, quartz glass square tubes transmit light from ultraviolet to infrared. They have a visible light transmittance of over 93%. In the ultraviolet region, the greatest transmittance can exceed 80%. Also, its electrical resistance is about 10,000 times that of ordinary glass. This makes it an excellent electrical insulator.

Applications

Lighting field, manufacturers can use them to make halogen, mercury, and xenon lamps. They can also make other types of lamps.

Heating, their high-temperature resistance makes them suitable for various heaters.

Scientific research, they are often used in tube furnaces, chemical reactors, and other devices.

In the semiconductor industry, they can hold processes like epitaxy, diffusion, and oxidation. Industries use quartz glass square tubes in ovens and dryers. They are also used in common products, like aquarium heaters and quartz tube foot warmers.
