Physical properties
Glass is made with quartz silica special industrial technology glass, it is a kind of very good base material.
Quartz glass has a series of excellent physical and chemical properties, such as:
1, high temperature resistant. Quartz glass
softening point temperature of about 1730 °C, 1100 °C in a long time, the short time use highest use temperatures up to 1450 °C.
2 and corrosion resistance. In addition to the hydrofluoric acid, quartz glass almost no and other acid
material produces chemical reaction, the acid ability is 30 times of ceramic, stainless steel 150 times,
especially in high temperature chemical stability, is any other engineering materials can match.
3, thermal stability. To adapt to the glass thermal expansion coefficient of tiny, can withstand severe
temperature changes, the quartz glass heated to 1100 °C or so, in room temperature water also won't burst.
4, Pervious to light performance is good
pervious to light good performance. Quartz glass in the ultraviolet ray to infrared spectral
bands have into the good pervious to light performance, visible light transmittance in 93% above, especially in
ultraviolet spectrum area, the biggest through rate can reach more than 80.
5, quartz glass electrical insulating
performance is good. Quartz glass resistance as common glass ten thousand times, is a very good electrical i
nsulating materials, even in normal temperature also has a good performance.
Application
quartz glass is formed due to its high temperature melt viscosity caused by high results. Used to make
semiconductor, electric light source device, half the communication device, laser, optical instrument, laboratory
instruments, electrical equipment, medical equipment and resistance to high temperature corrosion resistance of
chemical equipment, chemical, electronic, metallurgy, building materials and defense industry etc, used widely.
Jiangsu DongHaiXian quartz technology of long production quartz glass high precision and no bubble, the surface
is smooth, corrosion resistance, pervious to light quality good, especially for electro-microcopy, electronic, chemical, war industry and other optical instrument observation window window.
Note:
The size ,tolerance and shape can be customized.
