Cte borosilicate glass
WebColor: Clear. Max. Temperature: 400° F. Fabrication: Annealed. Also called Pyrex and Schott glass, this glass resists clouding and pitting and is highly chemical and heat resistant. With a low rate of thermal expansion, it stays dimensionally stable during changes in temperature. For technical drawings and 3-D models, click on a part number. WebThe borosilicate glass of usual laboratory glassware has a lower coefficient of thermal expansion than tungsten, thus it is necessary to use an intermediate sealing glass to get a stress-free seal. There are combinations of glass and iron-nickel-cobalt alloys ( Kovar ) where even the non-linearity of the thermal expansion is matched.

WebFused quartz, fused silica or quartz glass is a glass consisting of almost pure silica (silicon dioxide, SiO 2) in amorphous (non-crystalline) form.This differs from all other commercial glasses in which other ingredients are added which change the glasses' optical and physical properties, such as lowering the melt temperature. Fused quartz, therefore, has high … WebHigh transmission for visible to near infrared applications, the most common optical glass: UV Fused Silica (UVFS) 195–2100 nm: Moderate: Excellent homogeneity and low thermal expansion, high laser damage resistance: CaF 2: 170–8000 nm: High: High transmission for deep UV to infrared applications: MgF 2: 150–6500 nm: High
