Fire Bricks

Fireclay Bricks or fire bricks are the most widely used refractory bricks because of their great features: low thermal conductivity; good thermal insulation performance; high resistance to thermal shock, abrasion, chemical attack to provide long service life; easy operation and installation; broad usage and applications; and low price, etc. At KT Refractories we offer a comprehensive range of Fireclay brick/fire bricks consisting of 30-55% alumina, all of which exhibit excellent strength. For higher demands we offer a hard fired "Super duty" Fire clay-brick with a very high mechanical strength.

High density, low porosity fire clay brick is our featured product in this category. Due to its low apparent porosity rate, it has great features of strong resistance to erosion, high refractoriness under load, great cold crushing strength, high mechanical strength, etc.

KT Refractories in Houston, TX distributes Fireclay Bricks of the best quality at the most competitive prices worldwide.
