It has several important applications, mainly in the following aspects:
1. Chemical industry: zirconium Sponge is used to produce zirconium - based alloys and various zirconium compounds, which are widely used in the chemical industry. For example, zirconium - based alloys are used to make reaction vessels, heat exchangers, and pipelines, as they can resist corrosion by a variety of chemical media, ensuring the safety and durability of equipment in chemical production processes
2. Electronics industry: Some zirconium - containing materials prepared from industrial - grade zirconium sponge have excellent dielectric and piezoelectric properties. They are used in the manufacture of electronic components such as capacitors, piezoelectric sensors, and ceramic filters, which play an important role in the fields of communication, electronics, and information technology.
3. Metallurgical industry: In the metallurgical industry, zirconium sponge is often used as an additive to improve the performance of alloys. It can refine the grain size of metals, improve the strength, toughness, and corrosion resistance of alloys. For example, in the production of stainless steel, adding a certain amount of zirconium can enhance its resistance to pitting corrosion and crevice corrosion.
4. Ceramics and refractory materials: Zirconium dioxide, which can be derived from zirconium sponge, is an important raw material for manufacturing high - performance ceramics and refractory materials. It has high melting point, good chemical stability, and thermal shock resistance. It is used to make ceramic knives, ceramic bearings, and refractory bricks, which are widely used in the fields of machinery, metallurgy, and building materials.
