Hollow Alumina Sphere for Insulating Bricks
Product Description
Hollow Alumina Sphere for Insulating Bricks is a new type of high temperature insulation material which is made from industrial aluminum treated by smelting in an electric furnace. the crystal form is a-Al2O3 micro crystals.
Hollow Alumina Sphere for Insulating Bricks can be made into various shpes with the highest temperature 1800 ℃, which is of high mechanical strength, and the volume density is only one-half of corundum products.
There are mixed grade Hollow Alumina Sphere for Insulating Bricks and graded ball two types:
Mixed grade: 0.2-5mm
Graded grade: 0.2-1mm, 1-2mm, 2-3mm, 3-5mm.
