The characteristics of zirconium

 Zirconium has good heat resistance and corrosion resistance and is widely used in many fields. The main sources of zirconium ore are Australia and South Africa. These two countries produce 65% of the world's output. Zirconium ore is chemically stable, strong resistance to corrosion of steel, and the expansion rate is small. High thermal conductivity. It is widely used as a refractory material.

Zirconium is one of the most abundant elements on earth. But high-quality zirconium ore is limited. Other materials are difficult to replace zirconium raw materials. Therefore, recycling should be considered. The zirconium sand commonly used in the market is mixed with silica sand and coexists with magnetite such as ilmenite rutile and monazite. The world's largest producer is Australia, where mines are concentrated on the east and west coasts, as well as resource ores such as ilmenite and rutile. Zirconia materials used in the refractories are zirconia desilication from zirconia inclined zirconia and electrofused zirconia. South Africa's inclined zircon mines have dried up, and mine supply trends in Russia need to be watched. In addition, high-quality zircons with low radioisotopes are in a declining trend, which requires attention to supply trends as well as oblique zircons.
