| overview | calcium aluminate chemical formula CaAl2O4 (or CaO • Al2O3). Molecular weight 158.04. White monoclinic, triclinic or orthorhombic crystals. Melting point 1600 ℃, relative density 2.9825, refractive index 1.643, 1.665 and 1.663. Decomposed in water, soluble in hydrochloric acid, but insoluble in nitric acid and sulfuric acid. Calcium aluminate can be obtained by co-melting calcium oxide and alumina. Calcium aluminate can make Portland cement. Calcium aluminate is a series of inorganic compounds formed by sintering calcium oxide and alumina at high temperature. Due to its physical properties of high hardness and low melting point, it is mainly used in industry. In the metallurgical industry, calcium aluminate is used as a cleaning agent, and the desulfurization efficiency of calcium aluminate refining slag can reach 45.83 percent, which creates good conditions for refining clean steel. |
| Chemical reaction | Calcium aluminate powder reacts with hydrochloric acid to produce polyaluminum chloride in one step. During production, first add water to the reaction tank, open the stirring slurry, then quantitatively add hydrochloric acid, dilute to the required concentration, and then slowly add calcium aluminate powder for reaction. During the reaction, the temperature in the pool will gradually increase. When it exceeds 110 ℃, appropriate amount of water can be added to inhibit it, so that the reaction will not be intense and overflow. Add a small amount of water several times to maintain the normal required temperature. After adding calcium aluminate powder, react for another 2 hours, and when the PH test paper is greater than 3, water can be added to dilute to a density of 1.25-1.26. After the material is released to the sedimentation tank for precipitation, the supernatant liquid is a liquid product, and can also be dried by a dryer to obtain a solid polyaluminium chloride product. |
| market situation | calcium aluminate is made of bauxite plus limestone through crushing, calcination and other processes. the calcined calcium aluminate is usually condensed into blocks or large particles, which need to be further ground into calcium aluminate powder of the required particle size according to the needs of downstream customers. At present, calcium aluminate products on the market mainly include calcium aluminate for water treatment agent, premelted calcium aluminate for steelmaking, calcium aluminate for cement, etc. Calcium aluminate for water treatment agent is usually used to produce water purifier polyaluminum chloride. Calcium aluminate is used as raw material to produce water purifier polyaluminum chloride, which can shorten the process flow, simplify the operation steps, improve product quality, reduce costs and reduce capital investment. The main application fields of calcium aluminate downstream are water purifier (polyaluminum chloride), cement, steelmaking and other fields, of which polyaluminum chloride is the most important application field. The development of downstream applications has a decisive influence on the demand of calcium aluminate industry. Polyaluminum chloride is mainly used in drinking water purification and sewage treatment industries. In recent years, my country's drinking water safety has received the attention of residents. The urban drinking water purification industry has developed rapidly, and due to the increasing pressure of environmental protection policies, the sewage treatment market has developed rapidly, which has promoted the growth of the demand for polyaluminum chloride, which has driven the upstream calcium aluminate market. development. |
| Use | Mainly used as a raw material for the production of aluminum sulfate and polymerized aluminum, and is a substitute for aluminum hydroxide powder |
