| Thermal Performance | Optical Performance |
| The normal temperature of quartz glass is 1350 ℃, the softening point is 1750 ℃. Quartz glass small thermal expansion coefficient, 5.5* 10^(-7) ℃ , only 1/12 ~ 1/20 of common glass. The department standard sample to burn up to 1200 ℃ after rapid into cold water, repeated more than three times the crack is not permitted. | The special light performance of quartz glass is it can through far far-ultraviolet rays. It also can through Visible light and near infrared spectrum, small thermal expansion coefficient, good chemical stability, bubble, stripes, uniformity, birefringence can be rivaled with general optical glass, so it is working in virious harsh situation with high stability coefficient of optical essential optical material. |
| Chemical Performance | Mechanical Capacity |
| Quartz glass belong to acid materal, except hydrofluoric acid and thermal phosphoric acid to any other acid are characterized by inertia, is one of the best acid materal. Alkali and salt at room temperature on the degree of corrosion of quartz glass is minimal, so do not rule out using quartz glass in thers regents. |
The mechanical properties of the quartz glass is better than hard glass and ceramics glass,only brittleness is poorer. The theretical calculation of strength of the quartz glass is very high , which is about 24*103MPA, but the actual measured intensity lower than this value dozens of times. The main factors influencing the strength of the microcracks on the surface of the size and depth of influence is most obvious, fine grinding of quartz glass specimen is larger than that of coarse grinding , the flexural strength increased about 0.6 times; Followed by the internal defects, siternal defects,such as bubbles, impurities, uneven melting and residual stress. The strength of the quartz glass with increasees with the rising of temperature, the annealing temperature near the end of the peak.

Quartz glass use
(1) Quartz glass is the valuable material, when using, must take put down gently, be careful
(2) All kinds of quartz glass has a highest use temperature, should not be more than the temperature when using, otherwise it will crystallization or softening deformation
(3)if use at high temperature of quartz glass, must be wiped clean before use.Can use 10% of hydrofluoric acid or lotion soaked, and then clean with high pure water or alcohol.Thin gloves should be worn when operating, don't allow direct hit a quartz glass by hand
(4) Continuous use of quartz glass products, permitted under the high temperature for prolonging the life of the quartz glass and improve the heat resistance performance is good.Conversely, intermittent use of quartz glass products under high temperature, its use is limited .
(5) Quartz glass materials have high thermal stability, can withstand severe temperature changed.But the actual use, due to the residual strain and the product shape is different, have certain difference, thermal stability should be careful when using .
(6) Quartz glass acid material, high temperature when using strictly avoid with alkaline substances (such as water glass, asbestos, potassium sodium compounds, etc.) contact, otherwise will greatly reduce the crystallization resistance.
