Once cooled, the resulting coarse granular material is crushed and sized to meet the required specifications. Chemical zirconia is produced through the chemical reaction of caustic soda with zircon sand, followed by various chemical processes. Zirconia is a very hard material with an extremely high melting point.
The high purity zirconia powder production process was as follows. Plasma dissociated zircon is ground to a particle size between 45 and 75 µm and heated with concentrated sulphuric acid at 320 ºC for 4 hours. …

The zirconium-silicate mineral zircon is produced as a coproduct from the mining and processing of heavy minerals. Zirconium and hafnium metal were produced from zircon by two domestic producers, one in Oregon and the other in Utah. Eudialyte and gittinsite are zirconium silicate minerals that have a potential for zirconia production ...
The typical zirconium coating process also is a five-stage process (see Figure 2), but it is much different from the iron phosphate process. First, there are only two chemical stages: cleaning and coating; sealing is not required. Also, there are two rinses between the cleaning and coating stages, and only the cleaning stage is heated.
