How much temperature can refractory bricks resist?

The temperature that refractory bricks can resist depends on the type of refractory material used to make the brick and the specific composition of the refractory material. Generally speaking, refractory bricks can withstand temperatures ranging from about 1,200°C (2,192°F) to over 1,800°C (3,272°F). However, some specialized refractory materials can withstand even higher temperatures, up to 2,800°C (5,072°F) or more.

Here are some examples of the maximum temperatures that different types of refractory bricks can withstand:

1. Fire clay bricks: up to 1,500°C (2,732°F)

2. High alumina bricks: up to 1,800°C (3,272°F)

3. Silica bricks: up to 1,750°C (3,182°F)

4. Magnesia bricks: up to 2,000°C (3,632°F)

5. Zirconia bricks: up to 2,800°C (5,072°F)

It's important to note that the maximum temperature that refractory bricks can withstand is not the only factor that determines their suitability for a particular application. Other factors, such as thermal shock resistance, chemical resistance, and mechanical strength, must also be considered when selecting refractory bricks for a given application.
