Use in Antiperspirants. Aluminum zirconium â or, more precisely, aluminum zirconium tetrachlorohydrex gly â is used in antiperspirants because it has several qualities that reduce sweating. It is absorbed by the skin, where the ions of aluminum and zirconium cause the skin cells to swell.any antiperspirants contain aluminum zirconium. Although some people believe there to be a link between aluminum zirconium and Alzheimer's disease, but scientific research does not support this claim. Aluminum zirconium may be used in antiperspirants because it has qualities that can reduce sweating.
Zircon is the primary source of all hafnium. Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.ircon is also marketed as a natural gemstone, and its oxide is processed to produce the diamond simulant, cubic zirconia. Zirconium is used in nuclear fuel cladding, chemical piping in corrosive environments, heat exchangers, and various specialty alloys.
