The main component of alumina powder<\/a>, its quality largely determines the quality of corundum abrasives. Not only that, high-temperature calcined alumina powder has a wide range of uses. Alumina powder has good sintering performance, high conversion rate, and sodium content. low. The quality of the product is reliable, with high melting point, good thermal stability, high hardness, good wear resistance, high mechanical strength, good electrical insulation, and corrosion resistance. Then, what is the difference between aluminum hydroxide, which has a similar name to alumina powder ?How to proceed? Let’s take a look at it together:<\/p>\n

Alumina (Al\u2082O\u2083) is a high-hardness compound with a melting point of 2054\u00b0C and a boiling point of 2980\u00b0C. It is an ionic crystal that can be ionized at high temperatures and is often used to make refractory materials. Industrial Al2O3 is prepared from bauxite (Al2O3\u00b73H2O) and diaspore. For Al2O3 with high purity requirements, it is generally prepared by chemical methods.<\/p>\n

Aluminium hydroxide, the chemical formula Al(OH)3, is a hydroxide of aluminum. Aluminum hydroxide can react with acid to form salt and water, and it can react with strong base to form salt and water, so it is also an amphoteric hydroxide. The chemical formula Al(OH)3 is a hydroxide of aluminum. Because it shows a certain degree of acidity, it can also be called aluminate (H3AlO3). But the actual reaction with alkali is tetrahydroxyaluminate ([Al(OH)4]-). Therefore, it is usually regarded as metaaluminate monohydrate (HAlO2\u00b7H2O), which is divided into industrial grade and pharmaceutical grade according to its use.<\/p>\n

The difference between aluminum oxid<\/a>e and aluminum hydroxide powder:<\/p>\n

1. Their forms are different: aluminum hydroxide is a white precipitate, and aluminum oxide is a solid. This is the easiest aspect to distinguish, and it can be distinguished from the appearance.<\/p>\n

2. Different properties: aluminum hydroxide is an amphoteric hydroxide, and aluminum oxide is also an amphoteric oxide, and aluminum hydroxide is a product of aluminum hydroxide.<\/p>\n

The main way to distinguish them is to distinguish them from the appearance. In fact, in addition to the above two, it can also be judged by heating aluminum hydroxide, because the heated aluminum hydroxide can get alumina.<\/p>\n","protected":false},"excerpt":{"rendered":"
