Product Introduction
Pyrex glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. pyrex glasses are known for having very low coefficients of thermal expansion (~3 × 10−6 K−1 at 20 °C), making them resistant to thermal shock, more so than any other common glass. Such glass is less subject to thermal stress .
Pyrex glass has a very low thermal expansion coefficient (3.3 × 10−6 K−1),[3] about one-third that of ordinary soda-lime glass. This reduces material stresses caused by temperature gradients, which makes borosilicate a more suitable type of glass for certain applications Fused quartzware is even better in this respect (having a fifteen times lower thermal expansion than soda-lime glass); however, the difficulty of working with fused quartz makes quartzware much more expensive, and pyrex glass is a low-cost compromise. While more resistant to thermal shock than other types of glass, pyrex glass can still crack or shatter when subjected to rapid or uneven temperature variations.
