dark red quartz tubes ruby glass heaters

We are a manufacturer of quartz glass products for many years.

Our products include transparent quartz tubes,quartz rods,quartz plates,carbon infrared heating lamps and so on.

Quartz tubes have many good characteristics.

1.High temperature

Quartz glass softening point temperature is about 1730 ℃, can be used for long periods  under 1100 ℃, the highest short-term use temperature of 1450 ℃.

2.Corrosion resistance

In addition to hydrofluoric acid, the quartz glass hardly acids and other substances react chemically, and its acid capacity is 30 times,ceramic,stainless steel 150-fold, especially in high temperature chemical stability, are any other engineering materials can elsewhere in the world.

3.Thermal stability

Quartz glass thermal expansion coefficient is extremely small, can withstand severe temperature changes, the quartz glass heated to about 1100 ℃, Add room temperature water will not cracks/

4.Transmittance performance

Quartz glass in the entire UV to infrared spectral bands have better light tratransmission performance, visible light transmittance of 93% or more in, especially in the UV spectral region, the largest up to 80% transmittance.

5.Good electric insulation properties

Quartz glass resistance value equivalent to ten thousand times that of ordinary glass is an excellentelectric insulating materials, even at a high temperature also has a good electric performance.

They are widely used in solarenergy,semiconductor,medical, electronic instrument, 

optical industry,UV curing, observation window for furnace, lighting, photoelectron, military industry, metallurgy,chemistry, etc.
