Abstract

The invention provides a preparation method, device and application of spherical magnesium oxide, and belongs to the technical field of inorganic chemical industry. The method comprises the steps thata magnesium salt solution and an auxiliary solution are mixed and are prepared into a precursor solution or sol under the stirring condition; and the precursor solution or sol passes through a reaction device through carrier gas, and solid powder is collected and calcined so as to obtain a spherical magnesium oxide product. Magnesium oxide particles prepared through the method are controllable inmorphology, uniform in particle size and capable of realizing continuous preparation. The prepared spherical magnesium oxide can be used for metal ion adsorption and can also be used in the field ofantibacterial materials.

Description

technical field

[0001] The invention belongs to the technical field of inorganic chemical industry, and in particular relates to a preparation method, device and application of spherical magnesium oxide. Background technique

[0002] As an important functional inorganic material, magnesium oxide is widely used in the fields of metallurgy, electronics, catalysis, ceramics, coatings, medicine, adsorption, refractory materials and optical materials. Mineral direct pyrolysis method, chemical precipitation method, gas phase hydration method, carbonization method, ammonium bicarbonate method, spray pyrolysis method, hydrothermal method, sol-gel method and other methods are used for the preparation of magnesium oxide. However, there are still many problems restricting the development and application of high value-added magnesium oxide materials, such as long process flow, environmental pollution, irregular product shape, wide particle size distribution, and serious particle agglome...
