Advanced New Products-Tabular Alumina, Activated Alumina And PAC Have Been Put Into Productions.

As the "One Core" part of the "One Core and Two Wings" project, the three advanced new product lines of Functional materials Plant have put into production.

The New Products include Tabular Alumina,Activated Alumina and Poly Aluminium Chloride.

Tabular Alumina is a pure sintered -alumina material that has been fully densified by rapid-sintering without the use of sintering aids at temperatures in excess of 1800°C. Tabular Alumina has characteristic large, well developed hexagonal tablet shaped -alumina crystals of up to 200 µm length. The excellent thermal volume stability and thermal shock characteristics can be attributed to its specific microstructure: low open porosity and large crystals with closed spherical pores, which are entrapped upon re-crystallization during rapid sintering. Tabular alumina has extremely high refractoriness, high mechanical strength and abrasion resistance, very good chemical purity, excellent dielectric properties and good resistance against acid and alkali corrosion. Tabular Alumina is the aggregate of choice in unshaped and shaped high performance refractories. It is used in a variety of industries such as steel, foundry, cement, petrochemical, ceramic and waste incineration. Other common applications include its use in electrical insulators, kiln furniture and as a catalyst support. Ground Tabular is an excellent product to be used as a filler in epoxy or resin systems where high dielectric strength, thermal conductivity or abrasion resistance is desired.


Activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 m²/g. The compound is used as a desiccant (to keep things dry by absorbing water from the air) and as a filter of fluoridearsenic and selenium in drinking water. It is made of aluminium oxide (alumina; Al2O3). It has a very high surface-area-to-weight ratio, due to the many "tunnel like" pores that it has. Activated alumina in its phase composition can be represented only by metastable forms (gamma-Al2O3 etc.). Corundum (alpha-Al2O3), the only stable form of aluminum oxide, does not have such a chemically active surface and is not used as a sorbent.

Poly Aluminum Chloride water purification agent is a novel kind of efficient water purification agent produced employing advanced production technique with raw materials (High quality aluminum hydroxide, high purity hydrochloric acid and so on). The liquid product is colorless and transparent and the solid product is white or milky white, with low insoluble, low salinity, low iron content (≤ 100pm).
