1, zirconium has rich and colorful colors and has always been regarded as a gem, which plays a decorative role in human life. With the deepening of people's understanding of zirconium, zirconium is more and more widely used, mainly in the form of zirconium silicate and zirconia, and is used in ceramics, refractories and other fields. Only 3%-4% of zirconium ore is processed into metallic zirconium (or sponge zirconium), and then further processed into various zirconium materials.

2. Zirconium: Zirconium is a chemical element, the atomic number of the element symbol Zr is 40, and the simple substance is a high melting point metal, which is light gray. The surface of zirconium is easy to form a shiny oxide film, so its appearance is similar to that of steel. It is corrosion-resistant, soluble in hydrofluoric acid and aqua regia, and can react with nonmetallic elements and many metallic elements to form a solid solution at high temperature.
