High temperature resistant glass

When purchasing glassware, heat resistance is often a key consideration for consumers. This is especially true for household glassware, such as those produced by Xinghuo Glass, which often must withstand extreme heat and cold. Among various glass materials, borosilicate glass stands out for its exceptional heat resistance, making it the preferred choice for many households. So, why is borosilicate glass so heat-resistant? Today, Xinghuo Glass will explain this mystery. 1. Unique chemical composition The high-temperature resistance of borosilicate glass stems primarily from its unique chemical composition. Compared to ordinary soda-lime glass, borosilicate glass contains a certain amount of boron oxide (B₂O₃) and silicon oxide (SiO₂), with the boron oxide content typically exceeding 12%. The introduction of boron modifies the glass's coefficient of thermal expansion, enabling it to maintain stable physical properties even at high temperatures. Furthermore, the silicon dioxide in borosilicate glass provides excellent chemical stability and mechanical strength, further enhancing its high-temperature resistance. 2. Low thermal expansion coefficient The coefficient of thermal expansion (CTE) is an important indicator of a material's volume change with temperature fluctuations. Borosilicate glass has an extremely low CTE, only about one-third that of ordinary glass. This means that even in high-temperature environments, the volume change is minimal, making it less susceptible to cracking due to thermal stress. Whether used to hold hot water, tea, or even microwave heating, borosilicate glassware can easily withstand these conditions, ensuring safety. 3. Excellent thermal shock resistance Thermal shock resistance refers to a material's ability to resist breaking when subjected to rapid temperature changes. Borosilicate glass, thanks to its low coefficient of thermal expansion and uniform microstructure, exhibits excellent thermal shock resistance. Even when poured with boiling water immediately after being removed from the refrigerator, or rapidly cooled from a high-temperature environment, borosilicate glassware will not break easily. This property makes borosilicate glass an ideal material for everyday items such as drinking glasses, coffee cups, and mugs. 4. Other advantages of high borosilicate glass In addition to high-temperature resistance, borosilicate glass offers the following advantages: High transparency: As clear as crystal, showing the true color of the beverage and enhancing the drinking experience. Strong chemical stability: It is not easy to react with acids, alkalis and other substances, and no harmful substances will be precipitated after long-term use. Light and strong: It is lighter than traditional glass and has good impact resistance. Environmentally friendly and recyclable: non-toxic and harmless, in line with modern environmental protection concepts. These characteristics make high borosilicate glass the core material of Xinghuo Glass's high-end product line, and it is widely used in products such as heat-resistant glass kettles, coffee pots, and baking containers. 5.
