What Are Refractories - The Refractories Institute (TRI)

What Are Refractories? Refractories are ceramic materials designed to withstand the very high temperatures (in excess of 1,000°F [538°C]) encountered in modern manufacturing. More heat-resistant than metals, they are used to line the hot surfaces found inside many industrial processes. In addition to being resistant to thermal stress and
