    Medicinal Calcium Sulfate API Excipient Details

    Calcium Sulfate Usage and Synthesis Method Brief Introduction:
    Calcium Sulfate is used as a pharmaceutical excipient, CAS 99400-01-8, Calcium sulfate, with the chemical formula CaSO₄, is a common laboratory and industrial chemical. China manufacturer specializing in the export of pharmaceutical excipient Medicinal Calcium Sulfate, API Calcium Sulfate have reasonable price, short lead time and reliable quality.
    Calcium sulfate, with the chemical formula CaSO4, is a common laboratory and industrial chemical. In the laboratory, anhydrous calcium sulfate is a desiccant, and calcium sulfate dihydrate is a common gypsum. However, water containing calcium sulfate becomes permanently hard water. Calcium sulfate has a wide range of uses: Calcium sulfate dihydrate is gypsum, which can be used for surgical fixation, tooth mold and artificial bone production, art creation and interior decoration; sometimes used as a desiccant in laboratories; food grade Calcium sulfate is a food additive used to separate tofu and bean curd from soybean milk; it is used as a soil improver in gardening.
    White monoclinic crystal or crystalline powder. Odorless. Hygroscopic. It loses one molecule of crystal water at 128°C, and loses all water at 163°C. Soluble in acid, sodium thiosulfate and ammonium salt solution, soluble in 400 parts of water, less soluble in hot water, very slowly soluble in glycerin, almost insoluble in ethanol and most organic solvents. The relative density is 2.32. irritating. It usually contains 2 crystal waters and exists in the form of gypsum in nature.

    Calcium Sulfate Chemical Properties:
    Calcium sulfide and carbon dioxide can be generated by reacting with carbon at high temperature. Gypsum CaS
    O4·2H2O is a natural mineral, which is white, light yellow, light pink to gray transparent or translucent plate-like or fibrous crystals. It is brittle, loses 1.5H2O at 128°C, and loses 2H2O at 163°C. In industry, the raw gypsum is heated to 150°C to dehydrate the mature gypsum CaSO4·0.5H2O (or calcined gypsum), and it is converted into CaSO4·2H2O by adding water. Accordingly, it can be used for plaster bandages, making plaster models, chalk, handicrafts, and building materials. Gypsum is also used as a speed regulator in cement to control its hardening rate. Gypsum is also used in paint putty and paper filler, and it can be used as a coagulant for daily tofu. Gypsum is used in agriculture to reduce the alkalinity of the soil. Gypsum ore and coal can produce SO2 at high temperature for the production of sulfuric acid. The solubility of CaSO4 is not large, and its solubility shows a special state of first increasing and then decreasing. For example, the solubility at 10°C is 0.1928g/100g water (the same below), at 40°C it is 0.2097, and at 100°C it drops to 0.1619, which will cause the hard water dissolving calcium sulfate to scale in the high-pressure boiler (up to 400°C) and cause harm. Beforehand, use Na2CO3 to convert CaSO4 into a more insoluble CaCO3 precipitate (its solubility: 0.0015g) and remove it (to soften hard water). When the marble encounters dilute H2SO4, slightly soluble CaSO4 is formed on the surface of the marble to hinder the contact with the acid and stop the reaction, so CO2 cannot be produced with dilute H2SO4 and marble.
    Chemical equation: CaCO3+H2SO4===CaSO4 (slightly soluble in water)+H2O+CO2↑

    Nitrogen fertilizer production analysis trace carbon monoxide and carbon dioxide used as moisture absorbent, paint, artificial ivory, paint, paper, dyes, printing, metallurgy, water treatment. As a food additive and processing aid, drug. Used as cement raw material; used as cement retarder; gypsum is widely used in rubber, plastics, fertilizers, pesticides, paints, textiles, food, medicine, papermaking, daily chemicals, crafts, in addition to being widely used as building materials and cement raw materials. Art, culture and education departments. In areas lacking sulfur resources, it can be used to manufacture sulfuric acid and ammonium sulfate. Colorless and transparent gypsum can be used as optical material. It is the raw material for the manufacture of cement, calcium sulfate hemihydrate and sulfuric acid. Used as filler in paint and paper industry. Used as a chemical fertilizer in agriculture, it can reduce soil alkalinity and improve soil performance. It is also used as a tissue enhancer in canned tomatoes and potatoes, a hardener for brewing water, a flavor enhancer for wine, etc. Various models can be made for building materials and cement production, and it can be used as a plaster bandage in medical treatment. In addition, it can also be used to adjust the setting time of cement, as a white pigment for paint, as a filler and polishing powder for paper, and is also a commonly used desiccant. It is also used in metallurgy and agriculture. It is also used as a bread improver.
