Most commonly used for arches, wood fired tunnel or barrel ovens, kilns, fire boxes, and door arch ways in a pizza oven. According to their Alumina content, they fall into two main categories, all of which exhibit excellent strength and endurance:
- Fire clay bricks (Alumina content < 45%): low thermal conductivity, excellent thermal insulation performance, high resistance to thermal shock, easy to install and can be used in many applications.
- High Alumina bricks (Alumina content >50%): high temperature performance, high corrosion and wear resistance, high bulk density.
