 Abstract
In this study, zircon sand is separated into zirconia and silica by using the Ar- arc plasma refining. And then silica is removed from it by the microwave leaching method to produce a high pure zirconia. Plasma melting consist of two sequential processes; reduction process with Ar gas only followed by refining process with Ar- gas. After cooling in chamber. The solid phase obtained at were found to be composed of 20% sulfuric acid solution. The solution was used as a leaching solution with microwave irradiation to obtain a high purity zirconia.
