Alumina Hollow Ball Brick used the alumina hollow ball,corundum powder,and calcined powders mixed at definite proportion as raw material. After mixing, drying, forming, firing at high temperature shuttle kiln made. Physical and chemical index:

Item	FR-84	FR-90	FR-1.2	FR-1.5	FR-1.7
Al₂O₃ % ≥	84	90	98.5	98.5	98.5
Fe₂O₃ % ≤	0.8	0.5	0.3	0.3	0.3
SiO₂ % ≤	15	9	1.0	1.0	1.0
Bulk density, g/m3,≤	1.5	1.5	1.2	1.5	1.7
Porosity,%, ≥	58	60	62	60	58
CCS,Mpa, ≥	16	15	3	12	15
Thermal conductivity, 1000°C,( W/m.k )≤	1.2	1.15	0.95	1.05	1.15
0.1Mpa RUL,°C ≥	1650	1700	1700	1700	1700
Refractoriness,°C ≥	1800	1800	1800	1800	1800

Characteristic:1. High temperature resistance.2. Low thermal conductivity.3. Good thermal insulation.4. High strength.5. Can direct contact with flame.6. Good chemical stability (acid-base erosion resistance ).7. Low bulk density (lighter than the same kind of material ,thin kiln wall, low cost ) .

Application: Alumina Hollow Ball Brick are widely used in metallurgy, refractories, light industry, chemical industry, ceramic, glass, electronic industries.Can be used in cracking furnace, Hot Blast Stove, Shuttle kiln ,heating furnace, tunnel kiln, push board kiln, pot furnace, and kinds of electric furnace and electrical kiln lining and so on.
