Introduction of High Alumina Insulation Brick
Light Weight High Alumina Brick, also known as high-aluminium heat insulating brick, are used in building heat insulating walls or heat preserving walls, which is basically for preserving or insulating heat. Light weight high alumina bricks contain more than 48% alumina oxide. This kind of brick does not directly exposed to high temperature inside kilns or furnaces, it only built closely to the kiln wall as insulations. It is a good insulation refractory material, which has a high compressive strength, low thermal conductivity and good insulation quality.Technical Data of High Alumina Insulating Brick
