| 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. |
