Electrofused Zirconia Uses
Electrofused Zirconia has a wide range of applications. In the past, it was mainly used in refractory materials, ceramic color glaze and other fields. In recent years, the application of electrofused zirconia in many emerging fields such as color glaze and advanced ceramics has also developed rapidly. The details are as follows:
1. refractories
downstream market: electrofused zirconium can be used to prepare high temperature refractories, such as AZS electric melting brick, magnesium zirconium brick, chrome zirconium brick, etc., add stabilizer can enhance the thermal shock performance and corrosion resistance, the preparation of continuous casting materials, sizing nozzle, foam ceramic filter, etc., mainly used in glass, steel and other building materials industry.
With the optimization of the industrial structure of the building materials industry and the continuous conversion of new and old kinetic energy, positive results are gradually emerging. Outstanding performance in the steel, glass and other building materials enterprises benefit, sales profit margin increase. The business climate of the building materials industry also drives upstream such as refractory materials, carbon and other related fields. At present, the overall demand for fused zirconium in the downstream refractory industry has risen steadily.
2. ceramic glaze pigment
downstream market: fused zirconium can be used to prepare zirconium-based raw materials, such as zirconium praseodymium yellow, vanadium zirconium blue, zirconium iron red, etc. The amount of fused zirconium oxide accounts for more than 50% of the amount of pigment raw materials. In recent years, the localization of ceramic inkjet printers and ceramic inks has matured, and major ceramic manufacturers have fully popularized ceramic inkjet technology. The amount of traditional glaze pigment used is greatly reduced, and the amount of fused zirconia used as a raw material for glaze is also reduced. In order to seek living space, the traditional pigment will develop in the direction, and the quality requirements of fused zirconium will continue to increase.
3. wear-resistant material
Electrically fused zirconium is added with yttrium oxide and pressed to sinter at high temperature to improve the overall strength and density. It is made into abrasive material with excellent hardness, toughness and impact resistance. It is mainly used for grinding and dispersing high hardness materials, including electronic ceramics, magnetic materials, alumina, silicon oxide, zirconium silicate, titanium dioxide, medicine and food, pigments, dyes, inks, special chemicals and other industries. In addition, zirconia and alumina are mixed and melted to produce coarse ground particles of zirconium corundum. Uses: The production of zirconium corundum abrasives and molds can be used to polish steel and metal alloys. Its grinding efficiency can be increased by 2 to 6 times compared with ordinary grinding tools. Wear-resistant materials are mainly used in specific professional fields, and the overall market demand is relatively stable.
4. advanced ceramics
are used to prepare cerium-zirconium composite oxides for automobile exhaust purification catalysts. With the continuous upgrading of automobile exhaust emission supervision and related standards, the demand in this field has gradually increased in recent years;
Used for sintering setter plates for electronic ceramic components, it has the characteristics of high temperature resistance, high strength, good thermal shock stability, good high temperature chemical stability, and long service life, there is no chemical reaction and adhesion with the fired ceramic elements, so as to ensure the stability and consistency of the performance of electronic ceramic products and improve the qualified rate of fired products.
is used for mold coating: the inner layer of titanium alloy casting parts, turbine engine pulp sheets and golf balls, etc. The superior performance of zirconia with high strength, thermal shock resistance and low expansion coefficient can ensure the precision of castings.
Automobile brake pads: With the increasing popularity of domestic family cars, there is still a lot of room for demand in this field.
