WebAug 5, 2015 · In this article, we will discuss these properties as well as important processing temperatures. Thermal Property. Common Values of Borosilicate Glass. Linear Thermal Expansion. α = 30 - 60 x 10 -7 /°C. … WebGeneral guideline for determining thermal shock probability in glass: Coefficient of thermal expansion Thermal conductivity . Larger the value of the ratio, more likely damage will occur due to thermal shock. The value for thermal conductivity stays pretty much the same for all glass. Thus the coefficient of thermal expansion has the most effect.

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. 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. lithium batteries light bulb
