magnesium oxide

Messi Biology stated that magnesium oxide mainly includes industrial grade, pharmaceutical grade, food grade, etc. The main difference is that the content of various indicators is different, the purity of industrial grade is low, and the purity of pharmaceutical and food grade is higher. Generally, it is powdery or granular; the requirements for the content […]

The preparation method of the composite magnesium oxide powder for dental alginate impression material comprises the following specific steps: a. Choose magnesium hydroxide powder raw material, magnesium hydroxide content is 97.3%, CaO is 1.3%, SO4 is 0.3%, Cl is 0.10%, heavy metal is 9ppm, As is 3ppm, acid insoluble matter is 0.08%; The weight loss

Messi Biology stated that in magnesium manganese ferrite, magnesium oxide is the main raw material. In the manufacture of medium and high-grade soft magnetic materials, high-grade magnesium oxide must be used. The development of magnetic materials has promoted the technological progress of high-quality magnesium oxide production. The special function of nano-magnesia has once again triggered

Hebei Messi Biology Co., Ltd. stated that nano-magnesium oxide is a new type of high-function fine inorganic material. The main types are nano-powder, nano-film, nano-wire and nano-solid. Due to the particularity of its structure, it has different electrical, magnetic, thermal and optical properties than the body, thus opening up a series of new application fields.

Hebei Messi Biology Co., Ltd. stated that in order to overcome the defects of poor catalytic activity and poor stability of ruthenium-based ammonia decomposition hydrogen production catalysts in the prior art under medium and low temperature conditions, it provides a ruthenium-based ammonia decomposition hydrogen production catalyst for ammonia Application of decomposition to prepare carbon-free hydrogen.

Glass-ceramic is used in home appliance glass, induction cooker boards, and glass-ceramic casserole. Hebei Messi Biology Co., Ltd. said that adding magnesium oxide to glass-ceramic can adjust the crystallization temperature of the glass. At low temperature, it can slow down the decrease of glass viscosity, and at high temperature, it can accelerate the increase of

Tibet Mag stated that silicon steel grade magnesium oxide needs to meet the quality and technical indicators of MgO>98%, CaO<0.5%, and Cl<0.02%. The impurity CaO will be hydrated into Ca(OH)2 in the slurry and coated on the surface of the steel plate to absorb CO2 in the air to form CaCO3. Under the action of

Tibet Mag said, the production of silicon steel grade magnesium oxide is mainly based on seawater brine and minerals, etc. as raw materials. When producing with liquid raw material, we first use alkaline solution as precipitant to precipitate magnesium, and then further prepare magnesium oxide. Our country mainly adopts alkaline magnesium carbonate as intermediate brine

In 1994, the cellulose diacetate production line of Nantong Company was put into operation, and cellulose diacetate was localized for the first time. Subsequently, Nantong Company has undergone expansions one after another, and its annual production capacity of cellulose acetate has reached 200,000 tons, ranking second in the world in terms of production scale.
