Title:
APPLICATION OF HEAT-RESISTANT EXPLOSION-PROOF GLASSWARE OR GLASS DAILY NECESSITIES HAVING LOW DIFFERENCE VALUE OF HIGH-TEMPERATURE REGION THERMAL EXPANSION COEFFICIENT, LOW CRYSTALLIZATION SPEED, AND HIGH SOFTENING POINT
Document Type and Number:
WIPO Patent Application WO/2017/083998
Kind Code:
A1
Abstract:
An application of heat-resistant explosion-proof glassware having a low difference value of a high-temperature region thermal expansion coefficient, a low crystallization speed, and a high softening point, wherein the glass contains 0.01%-39% of aluminum oxide and 7%-20% of magnesium oxide according to percentage by weight; the content of silicon oxide is 2.51-4.8 times greater than that of calcium oxide; the content of calcium oxide is 0.7-2.3 times greater than that of magnesium oxide. The glassware has a softening point of 750℃-940℃ and a breaking strength of 70-240 MPa.
