Mullite Brick

Laurel Mullite bricks are outstanding refractory materials. With mullite as the main component, relying on the high melting point of mullite, they possess excellent high-temperature resistance and can operate stably in a high-temperature environment of 1600℃ - 1700℃. Their dense structure endows them with high mechanical strength, outstanding compressive and flexural capabilities, enabling them to effectively bear heavy pressure and impact. Meanwhile, they also have good thermal shock resistance, being able to maintain their own stability in the face of sudden temperature changes and not prone to cracking or spalling. In addition, they have strong chemical stability and can resist the erosion of most acidic and alkaline slags and molten metals. In high-temperature kilns of numerous industries such as metallurgy, glass, ceramics, and power, they are often used as lining materials to ensure the normal operation and efficient production of the kilns.

Product Details

Performance characteristics of mullite bricks:

1. Good high-temperature resistance: Mullite has a relatively high melting point, enabling mullite bricks to maintain stable physical and chemical properties in a high-temperature environment. They can withstand high temperatures ranging from 1600℃ to 1700℃.

2. High mechanical strength: With a dense structure, mullite bricks have high compressive strength and flexural strength. They can withstand significant pressure and impact force and are not prone to cracking or damage during use.

3. Good thermal shock resistance: In the case of sudden temperature changes, mullite bricks can still maintain good stability. They are not easily cracked or spalled due to thermal stress and can adapt to frequent heating and cooling processes.

4. Strong chemical stability: They have good resistance to most acidic and alkaline slags, molten metals, etc. They are not prone to chemical reactions with other substances at high temperatures, can effectively resist chemical erosion, and prolong their service life.
