The threshold stress intensity factor, , for sub-critical crack growth of borosilicate glass was measured in water environment using the interrupted static fatigue test. Bending tests with durations ranging from 1 h to 50 days were performed. Around 15 specimens were tested at each condition and ...
and because the rate of heat transfer through the glass is low, a steep temperature gradient is set up, which produces a correspondingtensile stress. This can cause breakage, because although glass is strong under compression, it is much weaker under tension:borosilicate glasscan therefore better ...
BOROSILICATE glass is widely used in electrochemical and corrosion studies because of its transparency, rigidity, ease of fabrication and, in particular, its resistance to chemical attack. Some disadvantages of the use of glass at very h... BUTLER, G,MERCER, A. D - 《Nature》 被引量: 2发表...
Soda Lime glass according to DIN 8902. For compressive stress with temperatures borosilicate circular sight glass up to max. 150 degrees Celsius, This is the most commonly used material due to its low cost. It can be easily toughened to effectively increase...
A maximum shear stress-based damage evolution law is used in describing the glass damage process under combined compression/shear loading. The impact test results are used in quantifying the critical shear stress for the borosilicate glass under examination. It is shown that with only two modeling ...
This paper describes an experimental test of the unified theory of thermal shock. A borosilicate glass (78.1%SiO-13.3%BO-4.7%NaO-3.4%AlO) subjected to ion-exchange in molten KNO, was used. The theory predicts the critical temperature difference for fracture initiation by thermal shock; however,...

The invention relates to a molding material for producing cast moldings for the foundry industry, at least comprising: a fire-proof molding material, a binding agent for hardening the molding material, and; a proportion of a borosilicate glass. The invention also relates to a method for producing...
Soda-lime glass and borosilicate glass are both types of common glass used in a variety of applications, but they have distinct properties that make them suitable for different purposes. 1. Composition: Soda-lime glass: Made primarily from silica (SiO₂), soda (Na₂O), and lime (CaO)...
