1) high purity: purity is an important indicator of quartz glass, ordinary quartz glass SiO2 content greater than 99.99%, high purity synthetic glass SiO2 content in more than 99.999%.

(2) thermal performance: the heat-resisting performance than any glass, quartz glass transparent quartz glass glass can withstand the work under the condition of high temperature 1100 ℃ ~ 1150 ℃ for long-term use.

(3) thermal stability: tiny quartz glass linear expansion coefficient, so have high thermal stability. Have to withstand severe temperature changes without cracking ability.

(4) mechanical properties: transparent quartz glass is 6 ~ 7 mohs hardness, compression of 14000 kg/cm2, the bending of 700 kg/cm2, the proportion of 2.903, mechanical properties than hard glass and ceramics are all well.

5. Chemical properties: quartz glass is good acid material, its chemical stability is equivalent to 30 times of acid-resistant ceramics, except hydrofluoric acid and phosphoric acid of more than 300 ℃, to other acid corrosion.

6 optical performance: quartz glass has good spectral characteristics, it can be through the ultraviolet and infrared light, high purity synthetic quartz glass can also through deep uv and resistance r rays.

All landowners electrical performance: quartz glass can hardly contain alkaline ion conductive, compared with other glass belongs to poor conductor. In the uhf with excellent properties. So as a solid insulating materials. Its electrical properties are far superior than its his material.
