Tabular corundum fireproof material ceramic plunger calcined alumina

Tabular corundum is high-purity sintered alpha-alumina spheres (in various sizes).Tabular alumina has been fired at extremely high temperatures(>1900℃) to reduce porosity to a very low level. This high-temperature process leads the growth of large plate-like, alpha-alumina crystals giving “tabular” alumina its name. Tabular Alumina Balls are carefully selected before packaging for size control, roundness and smooth surface.

Tabular alumina is the perfect refractory raw material.
● Tabular alumina can replace fused alumina and white fused alumina in some application.
● Tabular alumina can use in kiln furniture and for metal filtration.
● Tabular alumina can be used in a variety of industries, including steel, foundry, cement, glass, petrochemical, ceramic and waste incineration.

1).Our first choice is T/T. For a large order 40% T/T in advance is earnest money, the rest to be paid in 7-10 days after getting B/L copy. For a small order,100% T/T in advance.
2).Second choice is L/C. We can accept irrevocable L/C at sight. For a large order 40%T/T, 60%L/C. We couldn’t accept L/C for a small order. The best way of payment we advise is T/T, because L/C is very complicated and a lot of extra fee to give the bank.
3).The others: West Union, Paypal.
