Zirconium and its application
Since ancient times, zirconium has been regarded as a precious stone because of its colorful colors and plays a decorative role in human life. With the deepening of people's understanding of zirconium, the application of zirconium has become more and more extensive. Perhaps most people are relatively unfamiliar with zirconium, but it has penetrated into all aspects of our lives. For example, various buildings around, ceramics, knives, decorations, etc. that are indispensable in life, and even the military and nuclear power fields are also indispensable for zirconium.
There are many kinds of zirconium products and various forms. The initial mineral form is zircon sand. After caustic soda, water washing, etc., primary products such as zirconium silicate and zirconium oxychloride can be produced. Zirconia, industrial-grade zirconium sponge and other products; if the level of purification and separation technology reaches a certain level, it can be made into nuclear-grade zirconium sponge.
Zirconium has a wide range of applications, mainly in the form of zirconium silicate and zirconium oxide in ceramics, refractories and other fields. Only 3%-4% of zirconium ore is processed into metal zirconium (or sponge zirconium), which is further processed into various zirconium materials. Due to the small thermal neutron absorption cross section of metal zirconium, metal zirconium has excellent nuclear properties. Shell etc. Nuclear grade zirconium can be regarded as an important strategic metal for the country and is closely related to the development of the nuclear industry.
As an active metal, zirconium forms an oxide film at room temperature. This oxide film makes zirconium and its alloys have excellent corrosion resistance. At the same time, zirconium has good mechanical and heat transfer properties, coupled with significant cost advantages, making it an excellent corrosion-resistant structural material in today's petrochemical industry.
Zirconium used in chemical acid and alkali resistant equipment, military industry and electronics industry is called industrial grade zirconium. In terms of ease of processing, technological level and technological content, zirconium metal and its alloy products are at the top of the industrial chain.
Zirconia Structural Ceramics
Made from composite zirconia, including zirconia grinding media and zirconia structural parts, zirconia structural parts mainly include zirconia special ceramic valves, optical fiber connectors, ceramic knives, watch accessories, ceramic push scissors Sheets, textile porcelain, etc.
Nuclear grade zirconium
It is mainly used as a structural material for nuclear powered aircraft carriers, nuclear submarines and civilian power generation reactors, as cladding of uranium fuel elements, etc., and is an important strategic metal.
Industrial grade zirconium
Industrial grade zirconium is mainly used to make chemical acid and alkali resistant equipment, military industry, electronic industry, pipeline valve material, special high-strength and high-temperature alloy material, electric vacuum and getter for lighting bulb industry.
Firearms Grade Zirconium
It is used as a firearm sponge zirconium burner, as well as alloy additives and metallurgical deoxidizers, chemical industry, civil flash fireworks, etc.
Global zirconium consumption area
At present, China and Europe are the main consumer markets for zirconium, and China's demand for zirconium accounts for as high as 52%. China's nuclear power has entered a stage of rapid development, which has led to the demand for nuclear-grade zirconium. At the same time, China is a major producer and exporter of the world's ceramic industry, and zirconium silicate is the direct and main raw material for the ceramic industry. With the rapid development of China's ceramic industry in recent years, the demand for zirconium has also soared.
