Aluminum hydroxide is widely used and can be divided into industrial grade and medical grade according to its different uses. For these two different grades of products do not know how much you know and understand, we might as well take a look at the following introduction.
Molecular formula: AL (OH) 3 or AL2O3613H2O; molecular weight: 78; there are 325 orders, 800 orders, 1250 orders, 5000 orders four specifications.
Aluminum hydroxide is the largest and most widely used inorganic flame retardant additive. As a flame retardant, it can not only flame retardant, but also prevent smoke, not produce drops, and do not produce toxic gas. Therefore, it has been widely used, and the amount of use is increasing year by year.
Scope of application: thermosetting plastics, thermoplastics, synthetic rubber, coatings and building materials.
Medical level introduction:
The formula of aluminum hydroxide xerogel: Al (OH) 3; molecular weight: 78.
Use: used as the raw material of stomach acid for inhibiting gastric acid. It is often used as a compound preparation, such as vitamin U belladonna aluminum capsule, Aluminium Hydroxide Tablets and other major components, and also used for medicinal excipients.
Properties: white powder, odorless and odorless. Insoluble in water and ethanol, soluble in dilute inorganic acids such as hydrochloric acid.
Whether pharmaceutical level or industrial grade aluminum hydroxide, they play an important role in their respective fields. The two are better differentiated, and will not confuse users' choices.
