Description of Low-porosity Fireclay Bricks
Low-porosity fireclay bricks are a type of refractory brick made from high-quality fireclay that has been fired at a high temperature. They are known for their low porosity, which means they have very few air spaces or voids. This makes them very dense and resistant to heat, chemicals, and abrasion.low porosity fireclay brick.
