Its solubility is 0.02% (15℃), and it is easily soluble in acid and ammonium

Hebei Messi Biology Co., Ltd. stated that magnesium carbonate is an inorganic substance with a uniform appearance of white or milky white powder. It has good water resistance, compatibility, filling, adsorption and hygroscopicity. With its good properties, magnesium carbonate is often used as an alkaline agent, desiccant, color-protecting agent, anti-caking agent, carrier, leavening agent and

The process flow for preparing pharmaceutical and food grade heavy magnesium carbonate from hydromagnesite is as follows: ① Raw material preparation: crush and screen the hydromagnesite to obtain magnesite powder with a particle size of 0.5-2mm. ② Calcination: Calculate magnesite powder at 800-900°C to obtain calcined magnesium oxide. ③ Water-soluble: Dissolve the calcined magnesium oxide

Magnesium carbonate whiskers are an inorganic material with excellent flame retardant properties. Its flame retardant performance mainly comes from the following two aspects: Magnesium carbonate whiskers have high thermal stability and decompose at high temperatures to release carbon dioxide and water vapor, forming a heat insulation layer to prevent heat transfer and inhibit the spread

Radial spherical magnesium carbonate is a material with good adsorption, ion exchange and catalytic activity. It has wide applications in the fields of catalysis, adsorption, ion exchange and other fields. The preparation processes of radial spherical magnesium carbonate mainly include the following: 1. Sol-gel method: This method is to dissolve magnesium carbonate in an alkaline
