Calcium aluminate powder appears as a grayish-white solid powder, is readily soluble in acids, and exhibits high reactivity with aluminum oxide. When reacted with hydrochloric acid, it can effectively dissolve 90% of the aluminum oxide.

Currently, calcium aluminate powder is primarily used as a raw material for producing water treatment flocculants such as polyaluminum chloride and polyaluminum ferric chloride. It is also used, to a lesser extent, as a raw material for manufacturing refractory materials and refractory bricks.

Calcium aluminate powder is primarily produced using two types of raw materials: aluminum ore and travertine (also known as calcite). After being crushed and ground, these two ores are mixed in specific proportions and fed into a rotary kiln, where they undergo a high-temperature reaction to yield the finished calcium aluminate powder. Since calcium aluminate powder is produced through the reaction between aluminum ore and calcite, it boasts high contents of active calcium and aluminum oxide. In the production of polyaluminum chloride, after the aluminum oxide reacts with hydrochloric acid, it can be effectively dissolved; moreover, the active calcium further enhances the efficiency of the reaction.

The application of calcium aluminate powder in the production of polyaluminum chloride is an important raw material for manufacturing polyaluminum chloride. The quality and price of calcium aluminate powder directly affect the production cost and product quality of polyaluminum chloride; therefore, selecting a reliable and stable calcium aluminate powder is crucial.

Xintai Group: How to Determine the Purity of Polyaluminum Chloride by Color

Usually, when purchasing polyaluminum chloride, we assess its quality based on three key indicators: alumina content, water-insoluble matter, and alkalinity. However, the alumina content can be intuitively judged simply by looking at its appearance—let me share some useful information with you today.

White polyaluminum chloride is a drinking-water-grade, iron-free, high-purity, or food-grade polyaluminum chloride with a content of 31% or higher. Its main raw materials are aluminum hydroxide powder and hydrochloric acid, and it is produced via spray-drying. All of these products are high-end and thus command relatively high prices.

Polyaluminum chloride is used in wastewater treatment and drinking water treatment. Its content ranges from 28% to 30%. The raw materials for polyaluminum chloride used in drinking water treatment include alumina powder, hydrochloric acid, and calcium aluminate powder. There are two main production processes: the spray-drying method and the plate-and-frame filtration method. Drinking water treatment has stringent requirements for heavy metals. The brownish, earthy-colored polyaluminum chloride raw materials consist of calcium aluminate powder, hydrochloric acid, bauxite, and iron powder, with a typical content of around 26%. This type is primarily used in wastewater treatment. Due to its relatively high iron content, it appears dark brown. If the iron content reaches 3%, it is referred to as polyaluminum chloride ferric, and it proves highly effective in wastewater treatment.

Xintai Group’s manufacturer aims to provide users with effective water purification products that help reduce significant application costs.
