Buy Discount Factory High Purity Calcium Metal made in China. Harvest Enterprise is High Purity Calcium Metal manufacturer and supplier in China.Calcium Metal the main purpose of metallic calcium is to process into metallic calcium particles, and then make calcium iron wire or pure calcium wire, which is finally used in the refining of iron and steel. Its role is to desulfurize and deoxidize and increase the fluidity of molten steel and to promote the rapid rise of inclusions in molten steel, generally used for the production of high-quality steel.metallic calcium is used as a dehydrating agent in producing waterfree alcohol and used as desulfurizert in the petroleum industry , used to deoxidize or desulfurize in the metallurgical industry.However, calcium compounds have extremely wide applications, especially in the construction industry.

Part One: How to Make
1. Calcining marble (CaCO3), commonly known as calcined white, into quick lime (CaO);
2. Quickly mix quicklime (CaO) with aluminum powder (AL) and use the ball press machine to make flat balls with a length of about 4 cm;
3. Put the flat ball in the reduction tank with a high temperature of 1200 degrees, and then evacuate the reduction tank;
4. The aluminum powder and quicklime underwent displacement reaction under vacuum and high-temperature conditions to produce alumina and metal calcium steam;
5. The metallic calcium vapor condenses in the water-cooled section of the reduction tank to form metallic calcium crystals;
6. After cooling, the metal calcium crystals can be processed into metal calcium products of the required specifications, such as metal calcium particles and metal calcium powder.
Part Two: How to Get
Generally, there is three methods to get High Purity Calcium Metal. Reduction method, electrolytic method and calcium refining
1. The reduction method is the main method for producing metallic calcium. Generally, limestone is used as a raw material, calcined into calcium oxide, and aluminum powder is used as a reducing agent. The calcined crushed calcium oxide and aluminum powder (reducing agent) are mixed evenly in a certain proportion, pressed into a block, and reacted under 0.01 vacuum and 1050-1200 ℃ temperature to generate calcium vapor and calcium aluminate (alumina), The reduced calcium vapor crystallizes at 750-400 ° C.The crystallized calcium is melted under the protection of argon to obtain a dense calcium ingot. The recovery rate of calcium produced by the reduction method is generally about 60%.
2. The earlier calcium electrolysis method is a contact method. In this method, the raw material consumption is large, the solubility of metallic calcium in the electrolyte is high, the current efficiency is low, and the product quality is poor (about 1% of chlorine), etc. To improve these shortcomings, later contact method is improved to the liquid cathode method electrolysis.
3. Calcium refining: High-purity calcium can be obtained after industrial calcium is further processed by high vacuum distillation. Generally, the distillation temperature is controlled at 780-820 ° C, and the vacuum degree is 1 × 10-4. Distillation treatment is less effective in purifying chloride in calcium. Nitrogen compounds can be added below the distillation temperature to form double salts. By adding nitrides and purifying by vacuum distillation, the sum of impurity elements chlorine, manganese, copper, iron, silicon, aluminum, nickel, etc. in calcium can be reduced to 1000-100ppm, that is, 99.9% -99.99% high purity calcium metal.
