Description

technical field [0001] The invention relates to the field of glass material technology, in particular to a high-temperature-resistant glass and a preparation method thereof. Background technique [0002] Glass can be divided into oxide glass and non-oxide glass according to its main composition. Plastic, rubber, abrasive and other industries. [0003] With the gradual increase in the application of glass, the research on glasses with different properties has gradually become the focus of people's research, especially by changing the composition of the glass to make the glass have different properties. Zirconium dioxide has excellent thermal and chemical stability, high melting point, high boiling point, small thermal conductivity, high hardness, good wear resistance, insulator at room temperature, and high refractive index. Very high melting point, so limit its application in the field of glass. Contents of the invention [0004] The purpose of the present invention is ...
