What are the upstream raw materials of ammonium alum? What do the downstream products contain?

As a common chemical raw material, ammonium alum has been broadly applied in the manufacturing field. Its upstream and downstream related items are numerous and involve many fields. But The following will detail the upstream and downstream associated items of ammonium alum. Upstream items:



1. Aluminum sulfate: Aluminum sulfate is one of the main raw materials of ammonium alum, which is applied to prepare ammonium alum. Aluminum sulfate is able to be obtained by acidolysis of bauxite, alunite and other ores. From what I've seen, For example

2. Ammonium sulfate: Ammonium sulfate is another main raw material of ammonium alum, which provides the required nitrogen element to ammonium alum. Ammonium sulfate is able to be produced by the neutralization interaction of synthetic ammonia and sulfuric acid. Downstream items:



1. Polyaluminum chloride(PAC): ammonium alum is able to be applied as a raw material to the preparation of polyaluminum chloride. Polyaluminum chloride is a broadly applied inorganic polymer flocculant, frequently applied in aquatic environments treatment, papermaking, printing and dyeing and other industries. But

2. Aluminum ammonium sulfate: ammonium alum is able to be applied to prepare aluminum ammonium sulfate, it's a food additive, frequently applied as a leavening agent and stabilizer. Specifically

3. Aluminum nitride(AlN): ammonium alum is able to be applied as a raw material to the preparation of aluminum nitride. I've found that Aluminum nitride is a kind of ceramic material with excellent performance, which has the characteristics of high hardness, high thermal conductivity and high electrical insulation, and is able to be applied to manufacture high-temperature structural parts and electronic devices. Makes sense, right?. But

4. And In fact Aluminum hydroxide: Ammonium alum is able to be applied to prepare aluminum hydroxide. As an inorganic flame retardant, aluminum hydroxide is broadly applied in plastics, rubber, fabric and other fields. it's able to be seen from the above introduction that there are many upstream and downstream related items of ammonium alum, involving aquatic environments treatment agents, food additives, ceramic materials, flame retardants and other fields. The production and consumption of these items are closely related to ammonium alum, which together constitute the manufacturing chain in the field of raw materials to chemical production.
