Magnesium oxide is a kind of magnesium oxide, the chemical formula is MgO, the molecular structure is a typical sodium chloride structure, and magnesium atoms and oxygen atoms are arranged in sequence. Magnesium oxide is a high-performance fine inorganic material that can be widely used in the fields of catalysis, electronics and ceramics. Magnesium oxide, with its large specific surface area, is a promising catalyst support that can be applied to a variety of reactions, as well as a promising chemical adsorbent for destructive adsorption of various pollutants. In addition to the above-mentioned applications, magnesium oxide can also be used to make effect pigments and sensor materials under certain conditions due to its unique characteristics.
1. Preparation of Magnesium Oxide with Special Morphology
The microscopic morphology and properties of materials are often strongly correlated, so the morphology control of inorganic materials has become one of the hotspots in the field of materials research in recent years. In recent years, domestic and foreign reports on magnesium oxide with special morphology and microstructure, many experimental studies have found that magnesium oxide with special morphology has very effective applications in many aspects. Hebei Meixi Biological Co., Ltd. briefly introduces some The preparation of special morphology magnesium oxide is outlined.
1.1 spherical magnesium oxide
Magnesium oxide with a spherical structure is calcined from the precursor spherical basic magnesium carbonate or spherical magnesium hydroxide or spherical basic magnesium oxalate. Taking spherical basic magnesium carbonate as an example, the spherical structure of basic magnesium carbonate is formed by the accumulation of sheet-like basic magnesium carbonate. The basic magnesium carbonate is calcined, and the spherical basic magnesium carbonate is thermally decomposed to obtain spherical magnesium oxide [2].
