Feature function of quartz glass tube

Feature function of quartz glass tube
The optical function of quartz glass tube is unique, it can not only pass far ultraviolet light, it is all ultraviolet data superior, but also can penetrate through visible light and near infrared spectrum, the large coefficient is very small, the chemical stability is good, the bubble, the stripe, the uniformity, the birefringence can be compared with the ordinary optical glass tube, so it is in a variety of bad works. The industry has optical data with high stability and optical coefficient.
Physical function
1. High temperature resistance. The softening point of quartz glass tube is about 1730 degrees centigrade and can be used for 1100 days at a low temperature. The high temperature can reach 1450 degrees at a short time.
2. Corrosion resistance. In addition, quartz glass tube is almost no chemical reaction with other acid attacks. Its acid resistance is 30 times as high as ceramic, 150 times as high as stainless steel, especially at high temperature, which is incomparable to any other engineering data.
3. The heat stability is good. The large coefficient of habitual glass tube is very small, and the acceptable temperature changes, heating the quartz glass tube to about 1100 degrees Celsius.
4. The light transmittance is good. Quartz glass tube has a good transmittance in the whole spectral band of ultraviolet to infrared. The transmittance of the visible light is above 93%, especially in the ultraviolet spectrum area, the high transmittance can be over 80.
5. The electrical insulation of quartz glass tube is good. Quartz glass tube has a resistance value of ten thousand times that of ordinary glass tube. It is an excellent electrical insulating material and has outstanding electrical functions even at room temperature.
Use of planning:
It is used to make semiconductors, electro-optical sources, semi conductance communication equipment, lasers, optical instruments, laboratory instruments, electrical equipment, equipment and high temperature and corrosion resistant chemical instruments, chemical, electronic, metallurgical, building materials, and national defense industries. Especially suitable for optical, electronic, chemical, military and other optical instruments observation window glass.
