View Product Description

Introduction of High Alumina Insulation Brick  Light Weight High Alumina Brick, also known as high-aluminium heat insulating brick, 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.High Alumina Insulation Brick Features 1. High refractoriness, can reach 1650-1800ºC 2. High mechanical intensity. 3. Low levels of iron and other impurities. 4. Good thermal shock resistance. 5. Chemical stability. 6. High porosity, low volume density, good thermal insulation effect,energy-efficient. 7. Low thermal conductivity, stable quality. 8. Excellent thermal shock resistance. 9. Strong resistance to the corrosive gas and slag.
