As a rare material, zirconium is regarded as a more precious aerospace material than titanium due to its amazing corrosion resistance, extremely high melting point, ultra-high hardness and strength and other characteristics. It is mainly exacted from zircon sand and widely used i aerospace, military industry, nuclear reaction and atomic energy fields. With the rapid development of electronics, national defense technology, information industry and emerging materials industry, zirconium chemicals are playing an increasingly important role in the high-tech fields at home and abroad, and the demand is growing rapidly.
