Pyrex and Kimax glass typically contain an oxide of which element that gives the glass a small coefficient of thermal expansion?

Question

Quizplus · Accepted Answer

Pyrex and Kimax glass contain boron oxide which gives them a small coefficient of thermal expansion. This means that the glass can resist sudden changes in temperature without cracking or breaking. Sodium and lead are not typically used in these types of glass, and arsenic is not commonly used in glass manufacturing due to its toxicity.
