These components create a structure with a very low coefficient of thermal expansion, making it highly resistant to thermal shock compared to standard soda-lime glass. While this property is advantageous for applications involving rapid temperature changes, such as laboratory equipment and high-intensity lighting, it presents a significant challenge for laser marking. The material's low thermal expansion means that the localized heat from a laser can induce immense internal stress, often resulting in micro-fractures, chipping, or catastrophic failure. This analysis explores the fundamental borosilicate glass properties, focusing […]
