Specifically refractories must be able to withstand temperatures above 538°C (1000°F). Refractories are mechanically strong and heat resistant to withstand rapid temperature change and corrosion and erosion by molten metal glass slag and hot gas. Refractories are used in kilns furnaces boilers incinerators and other applications.
