Palm corundum brick and difference of white corundum brick

Palm corundum brick and white corundum brick are the corundum brick of two kinds of different types, they have the place with different the following:
Palm corundum brick is with electric frit palm corundum is main raw material, classics high pressure shapes, high temperature is firing, have thermal shock stability tall, porosity is low, low expand, fight fuse-element vapour is amiable body aggressivity can be good.
White corundum brick is raw material with industrial oxidation aluminium powder, make via the refrigeration after fusion of high temperature of 2000 degrees of above in electric arc, via smashing type selecting, magnetic separation goes iron, screening becomes a variety of size, its quality of a material compact, hardness is tall, it is a kind of neuter and fireproof raw material, whiteness of colour and lustre, glittering and translucent and dazzing, have bulk density big, porosity is low characteristic.

Color: Palm corundum brick is brown or of palm red, and white corundum brick is white.
Hardness: Corundum is one kind very hard mineral, hardness is in mineral in the in front of in the rank, be next to diamond. The hardness of palm corundum is about 9, bai Gangyu's hardness is taller, it is about 9.5.
Density: The density of palm corundum is 3.95-4.10 G/cm3 about, bai Gangyu's density is higher, it is 3.96-4.00 G/cm3 about.
Wearability: Bai Gangyu's wearability is taller than palm corundum, because Bai Gangyu is more hard,mix compact.
Use a field: It is better to be had as a result of palm corundum brick fight concussion and wear-resisting function, commonly used the production that waits for fireproof material at the metallurgy equipment such as kiln of high temperature agglomeration, converter and cement kiln, the chamber of a stove or furnace. And white corundum brick has very tall hardness and wear-resisting property, use at treatment of cutting of high speed abrasive and abrasive to grind normally make wait for a domain.
Those who need an attention is, the function of palm corundum brick and white corundum brick and utility still pledge with particular material the element such as composition, workmanship, manufacturer home is concerned, because this is when choice and application,need considers integratedly.
