Reactive magnesium oxide is familiar to everyone, the activity degree is very high, the size of the activity is an important physical and chemical properties of magnesium oxide, and it is also an important indicator of magnesium oxide. Determination of reactive magnesium oxide has aqueous method, conductivity method, iodine adsorption method, citric acid method, etc., […]

With the rapid development of the modern chemical industry and the continuous improvement of technology, many new materials are widely used in various fields, among which, magnesium oxide has been widely used in the adhesive industry because of its own advantages of stable chemical properties, good thermal stability and good adhesion and strength. Take neoprene

Magnesium oxide can improve the chemical stability and mechanical strength of the glass, and can reduce the crystallization tendency of the glass. If magnesium oxide is used instead of calcium oxide, it can reduce the crystal disappearance temperature, reduce the devitrification tendency and crystallization speed of the glass, and also have a positive effect on

Phosphor is in the ultraviolet, visible radiation and electric field caused by the action of luminescent substances, mainly used in certain electric light sources, generally refers to the mercury vapor discharge of ultraviolet radiation produced when converted to visible light or the desired wavelength of ultraviolet light-emitting substances (traditional fluorescent lamps, energy-saving lamps). But the

Magnesium oxide is generally divided into light magnesium oxide and heavy magnesium oxide two kinds, light volume fluffy, white amorphous powder, odorless, tasteless and non-toxic, density 3.58g/cm3, insoluble in pure water and organic solvents, solubility in water due to the presence of carbon dioxide and increase, can be dissolved in acid, ammonium salt solution. Scorched

Reactive magnesia, also known as light-burned magnesia or caustic magnesia, is magnesia formed by calcining magnesium compounds below 900°C. The chemical activity of magnesia can be expressed by iodine absorption value (adsorption performance index). The higher the iodine value, the lighter it is. When the iodine absorption value is 120-180mg/g, it is called high-activity magnesia;

Magnesium oxide is widely used and can be seen everywhere in our basic necessities of life. Today I will talk about the application of food and pharmaceutical grade magnesium oxide in the cosmetics industry. Magnesium oxide is used in the production process of many cosmetics and skin care products (such as sunscreen, loose powder, mask,
