What is Magnesium Carbonate Powder?

Magnesium Carbonate Powder is a white, odor free powder with two common forms: amorphous powder as well as monoclinic crystal. It has the features of non-combustion as well as light texture, and also can be utilized for thermal insulation and also heat resistant fire insulation materials. Asbestos quality magnesium carbonate is a superb protecting product, utilized in shipbuilding as well as boiler production and also other fields, and can likewise be used in the manufacture of sophisticated glass products, magnesium salts, pigments, paints, fire-retardant layers, printing inks, porcelains, cosmetics, toothpaste and other everyday chemicals and pharmaceutical items.

Applications of Magnesium Carbonate Powder

Application 1.
The method of utilizing Magnesium Carbonate Powder coarse ore to prepare high-purity magnesium oxide is as follows:

1. The crude magnesium carbonate ore, the primary product of Longmucuo and Jiezechaka salt lake mixed with brine (sulfate type and carbonate type salt lake mixed with brine), is used as raw material, and the main component in the raw material component is 67.2% 4MgCO3·Mg( OH)2·5H2O, the minor components are NaCl and a small amount of sulfate and boron-containing compounds 0.27% (calculated as B) and so on. First, the coarse magnesium carbonate ore is crushed and sieved with a 60-mesh screen, and the soluble impurities are removed by traditional washing and filtration methods (for example, deionized water is used to prepare a slurry with a liquid-solid ratio of 5:1 by weight, Filter in vacuo after mechanical stirring, twice).

2. Add a sodium bicarbonate solution with a mass concentration of 9% to the Magnesium Carbonate Powder coarse ore that is screened and remove soluble impurities as a boron remover, wherein, according to the mass ratio, the sodium bicarbonate solution and the magnesium carbonate coarse ore are The liquid-solid ratio is 10:1, and the magnesium carbonate coarse ore is dissolved in the sodium bicarbonate solution to form the first slurry.

3. Putting the first slurry into the reactor for hydrothermal reaction to obtain the second slurry. The temperature at which the hydrothermal reaction was carried out was 180°C, and the reaction time was 10 hours.

4. The second slurry is filtered, washed and dried to obtain anhydrous Magnesium Carbonate Powder.

5. The anhydrous magnesium carbonate is calcined to obtain high-purity magnesium oxide. The firing temperature was 1200°C, and the firing time was 10 hours.

After testing, the purity of the prepared magnesium oxide is as high as 99.17%, and the boron content is 0.0069%.

Application 2.
A process method for producing rare earth magnesium alloy by basic Magnesium Carbonate Powder, the concrete steps are:

The basic magnesium carbonate with MgO content of 41.7%wt was put into a stirring reaction kettle, and hydrochloric acid was added to carry out stirring reaction. After the solid was completely dissolved, a magnesium chloride solution was obtained, which was evaporated by heating and concentrated to a mass fraction of magnesium chloride of 40.1%. Cool to 20°C at a rate of 2°C/min to precipitate crystals, separate by suction filtration, and dry for 1.5h to obtain high-purity magnesium chloride hexahydrate crystals. The obtained high-purity magnesium chloride hexahydrate and lanthanum chloride heptahydrate are uniformly mixed according to a weight ratio of 1:0.10, as an electrolysis raw material, loaded into a graphite crucible, and a potassium chloride and sodium chloride mixture of 1:1 with a mass ratio is As the electrolyte, the liquid rare earth magnesium alloy is used as the sinking cathode, and the graphite crucible is used as the anode. The electrolytic raw materials after heating and melting are continuously added dropwise to the electrolyte. The current is 1000A, the voltage is 5V, and the temperature is 800 ℃. By direct current electrolysis, rare earth magnesium alloy is obtained at the cathode. After EDS detection, the lanthanum content of rare earth magnesium alloy is about 5%.

Introduction of Lightweight Magnesium Carbonate Powder Preparation Process

With the increasing demand for lightweight Magnesium Carbonate Powder, the preparation method of high-quality light magnesium carbonate has very important theoretical significance and application value. In industry, we can use the suspension of industrial by-product magnesium hydroxide to react with carbon dioxide to prepare light magnesium carbonate, and the sodium sulfate and other substances contained in the magnesium hydroxide suspension will not react with carbon dioxide gas.

Using light-burned dolomite powder as raw material, a highly active dolomite powder digestive solution is prepared by digestion, and then the light Magnesium Carbonate Powder is prepared by atmospheric secondary carbonization method. Various influencing factors in the preparation process are studied. , we have determined the optimal process parameters, and conducted a preliminary discussion on its mechanism of action. The results show that the optimum process conditions for digestion are as follows: the light-burned dolomite material is ground into small particles with an average particle size of 1.78 μm, digested for 30 minutes at a water temperature of 70 °C, and then cooled and precipitated at room temperature for 24 hours. the digestive juice;

The optimal process conditions for carbonization are: using atmospheric pressure secondary carbonization method, the pH value of the first and second carbonization is pH=10, pH=9, and the CO partial pressure of primary and secondary carbonization is Pco =0.03MPa, Pco=0.1MPa, the carbonization liquid concentration is 25g.L, and the stirring speed is 400rpm; under the condition of the pyrolysis temperature of 50℃, the prepared length is about 6060μm, the cross-sectional diameter is about 2μm, and the whiteness is 97.3 , light magnesium carbonate with a magnesium oxide content of 41.0% and a calcium oxide content of 0.4%. The recovery of light magnesium carbonate product was 54.3%. When the pyrolysis temperature is 60 °C, light magnesium carbonate in the form of flakes or rose petals can be prepared; when the pyrolysis temperature reaches 70 °C, spherical light Magnesium Carbonate Powder with a diameter of about 40 μm can be prepared.

The change of the pyrolysis temperature will affect the pyrolysis speed and solution structure of the magnesium bicarbonate solution. After two-dimensional nucleation or the enhancement of the intermolecular bonding force, a sheet or spherical light magnesium carbonate will be formed; when the heavy magnesium water is at 50 When pyrolysis is carried out at ℃, the rod-shaped light magnesium carbonate without additives will agglomerate. The addition of sodium citrate can make the particles of the rod-shaped light Magnesium Carbonate Powder evenly distributed, and the addition of ethanol can reduce the aspect ratio of the light magnesium carbonate. , the addition of magnesium chloride can increase the crystal length of rod-shaped light magnesium carbonate. The main reason for this is that the addition of additives can change the crystallization behavior of the lightweight Magnesium Carbonate Powder and the supersaturation of the solution.
