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,

Magnesium oxide is a high-performance chemical material with excellent chemical inertness, heat resistance, insulation and thermal conductivity. Especially its good high temperature oxidation resistance and moderate alkalinity make it widely used in many fields. In addition, the oxygen vacancies and single electrons in magnesium oxide also endow it with strong electrophilicity, which provides an important

1. Overview In recent years, the cobalt industry chain has changed, from cobalt ore to cobalt hydrometallurgy crude cobalt hydroxide, and its import ratio has increased rapidly. As the largest smelting and processing country, China has a huge import volume. Research The crude cobalt hydroxide production process is conducive to further estimating the cobalt production
