Quartz glass is made of silica special industrial technology glass, is a very good base material. Quartz glass has a series of excellent physical and chemical properties such as:
1, high temperature. Quartz glass softening point temperature of about 1730 ºC, can be used at 1100 ºC for a long time, the shortest time the maximum temperature of up to 1450 ºC,
2, corrosion resistance. In addition to hydrofluoric acid, the quartz glass is almost no chemical reaction with other acids, the acid resistance is 30 times the ceramic, 150 times the stainless steel, especially at high temperature chemical stability, is any other engineering materials are not Match.
3, good thermal stability. Quartz glass thermal expansion coefficient is minimal, can withstand severe temperature changes, the quartz glass heated to about 1100 ºC, into the room temperature water will not burst.
4, good light transmission performance. Quartz glass in the ultraviolet to infrared spectrum of the entire spectrum have better light transmission performance, visible light transmittance of 93% or more, especially in the UV spectrum, the maximum transmittance of up to 80 or more.
5, good electrical insulation performance. Quartz glass resistance value equivalent to 10,000 times the ordinary glass, is an excellent electrical insulation material, even at high temperatures also have good electrical properties

Product use recommendations
One, storage
    Should be kept in the original box, at least the original production plant should be retained packaging materials. Quartz tube should be removed when used in the packaging, because the moisture and dust will damage the purity and performance of quartz glass tube. Storage of quartz materials in the warehouse requires clean and dry.
    Second, cleaning
Quartz material cleaning should be placed in the water with a dissolving agent in the water, cleaning grease, and then washed with deionized water immersion 5-10% (volume ratio) of hydrofluoric acid to wash 5-10 minutes, Deionized water to wash, and quickly make it dry without producing water marks.
    Third, the use of ordinary quartz glass tube temperature
Quartz glass is a supercooled liquid, is amorphous, like paraffin, only softening temperature range, the higher the temperature the smaller the viscosity, the more easily deformed, ordinary quartz tube at 1200 ºC, the viscosity of 1013 Pa, long-term use will bend. Improve the purity, reduce the hydroxyl, increase the thickness can reduce the amount of deformation. If the quartz tube is used for more than 1100 ° C for a long period of time, the furnace temperature can be increased to 1200 ° C before starting to use, rotating 90 ° every 2 hours, so repeated heating 20-30 hours, and then put into use, can reduce the amount of deformation.
    Fourth, to improve the life of quartz glass
Quartz glass damage, mainly cooling burst. Because the quartz glass at high temperatures will be converted into square quartz crystal. Square quartz at 240 ºC when the crystal conversion, accompanied by changes in density and volume, resulting in quartz glass burst, if the furnace temperature above 500 ºC, quartz glass can be used for a long time will not be damaged. Quartz glass crystal (commonly known as crystal), from the surface, the surface contamination (for example: without a direct touch of gloves) will accelerate the crystallization; Diffusion furnace refractory material selection, containing alkali metal oxide refractory materials will accelerate the crystallization Can be accelerated hundreds of times to thousands of times; the higher the temperature the faster the crystallization rate, below 1000 ºC, quartz glass is basically not crystallization, 1100 ºC above will accelerate the crystallization, 1400 ºC 6 hours, the crystal layer should be less than 100 microns For qualified products.
