Zirconium Application Areas

Santech Applied Technology Co.,Ltd | Updated: Oct 19, 2017

Since ancient times, because zircon has a rich and colorful color, has been used as a gem, in human life plays a decorative role. With the increasing awareness of zircons, the use of zirconium is becoming more and more extensive, and perhaps most people are more unfamiliar to zirconium, but it has penetrated into all aspects of our lives. For example, around the various buildings, life essential ceramics, knives, decorations, etc., and even military, nuclear power and ultimately the zirconium figure.

Zirconium products are rich in various forms, the initial form of mineral zircon sand, after caustic soda, washed and other treatment, can produce zirconium silicate and zirconium oxychloride and other primary products; continue to calcination, chlorination, reduction can also be made two Zirconium oxide, industrial grade sponge zirconium and other products; if the purification, separation technology to a certain level, can be made of nuclear level sponge zirconium.

Zirconium is widely used in the field, mainly in the form of zirconium silicate, zirconia used in ceramics, refractories and other fields. Only 3% -4% of the zirconium ore is processed into metal zirconium (or sponge zirconium), and then further processed into a variety of zirconium. As the zirconium has a small thermal neutron absorption cross-section characteristics, making the metal zirconium has excellent nuclear properties, nuclear grade zirconium is the application of this feature will be used as nuclear-powered aircraft carriers, nuclear submarines and civil power generation reactor structural materials, uranium fuel components Shells and so on. Nuclear grade zirconium can be regarded as an important national strategic metal, closely related to the development of nuclear industry.

Zirconium as an active metal, at room temperature will form an oxide film, this layer of oxide film makes zirconium and its alloys have excellent corrosion resistance. At the same time, zirconium has good mechanical and heat transfer performance, coupled with significant cost advantages, making it an excellent corrosion resistant structural material for today's petrochemical industry.

In the chemical acid and alkali equipment, military, electronics industry in the application of zirconium is called industrial grade zirconium. From the processing of the degree of difficulty, the level of technology and scientific and technological aspects, metal zirconium and its alloy products in the top of the industrial chain.

Zirconium silicate

Zirconium silicate is an important variety in traditional zirconium products. Products to zircon sand as raw material, grinding, calcination, powder can be obtained after, is a high-quality, cheap ceramic glaze opacifier, mainly used for building ceramics, ceramics and ceramics for daily use of color glaze Production, in the high-grade refractory materials, precision casting, emulsified glass and other industries are also widely used.

Zirconium oxychloride

Production of other zirconium products such as zirconium dioxide, zirconium carbonate, zirconium sulfate, composite zirconia and zirconium hafnium separation of the preparation of metal zirconium hafnium main raw materials, can also be used for textile, leather, rubber additives, metal surface treatment agent, paint desiccant, Refractories, ceramics, catalysts, fire agents and other products, in recent years, China's annual output of more than 90,000 tons. Zircon sand is the main raw material of zirconium oxychloride.

Fused zirconia

Referred to as fused zirconium, fused zirconia, mainly used for the production of glaze and refractory materials. Due to the high content of impurities in fused zirconium, the use is limited.

Zirconium sulfate

Leather tanning agents, wool processing agents and paint surface oxidants important raw materials can be used as catalyst carrier, amino acids and proteins, precipitants and deodorants, but also the preparation of zirconium chemicals and metal zirconium, hafnium intermediate raw materials.

zirconium dioxide

Zirconia all-ceramic non-toxic, odorless white solid, alkali solution and many acidic solutions are sufficient stability for precision ceramics, electronic ceramics, optical lenses, glass additives, electrolytic zirconium brick, ceramic pigments, Enamel, artificial gemstones, refractory materials, grinding and polishing industries and products.

Composite zirconia

Also known as semi-stable, stable zirconia, is non-toxic, odorless white powder, chemical stability, specific surface area control, is the manufacture of various types of special ceramics, senior refractory materials, optical communications devices, new energy materials,

Zirconia structural ceramics

Made of zirconium oxide as raw material, including zirconia grinding and zirconia structural parts of two kinds of products, zirconia structural parts, including zirconia special ceramic valves, fiber optic connectors, ceramic knives, watch accessories, ceramic push scissors Tablets, textile porcelain and so on.

Nuclear grade zirconium

Mainly used as nuclear power aircraft carriers, nuclear submarines and civil power generation reactor structural materials, uranium fuel components, etc., is an important strategic metal

Industrial grade zirconium

Industrial grade zirconium is mainly used in the production of chemical acid and alkali equipment, military, electronics industry, pipeline valve materials, special high strength and high temperature alloy materials, electric vacuum and lighting bulb industry getter.

Firearms grade zirconium

For firearms sponge zirconium burner, but also for alloy additives and metallurgical deoxidizer, chemical, civilian flash fireworks.
