Product Information
Sillimanite bricks are high-performance refractory bricks used in a variety of high-temperature industrial applications. They are made of natural or synthetic Sillimanite minerals, which are composed of aluminum silicate. And they have excellent refractory properties, including high refractoriness, high thermal shock resistance, and excellent creep resistance. Furnaces, boilers, kilns, and incinerators are all use them because of their special qualities.
The importance of Sillimanite bricks in the refractory industry cannot be overstated. Their thermal shock and abrasion resistance make them perfect for high-temperature situations. They have low heat conductivity, therefore they can resist high temperatures without degrading or losing shape. Industrial engineers and manufacturers who need materials to survive extreme temperatures and hostile environments value them.
