Application and advantages of fused zirconia

1、 Application of fused zirconia

1. High temperature refractory materials

For example, AZS fused bricks, magnesium zirconium bricks, chrome zirconium bricks, etc., adding stabilizers can enhance thermal shock performance and corrosion resistance, and prepare continuous casting materials, sizing nozzles, foam ceramic filters, etc., which are mainly used in glass, steel and other building materials industries;

2. Colorants for ceramic glaze

For example, zirconium praseodymium yellow, vanadium zirconium blue, zircon iron red, etc., the amount of fused zirconia accounts for more than 50% of the amount of color raw materials used;

3. Wear-resistant material

Electromelted zirconium is added to yttrium oxide for pressing and sintering at high temperatures to improve overall strength and density, making it into grinding materials. It is mainly used for ultrafine grinding and dispersion of high hardness materials, including electronic ceramics, magnetic materials, alumina, silicon oxide, zirconium silicate, titanium dioxide, pharmaceutical and food products, pigments, dyes, inks, specialty chemicals, and other industries;

4. Burning plate for firing electronic ceramic components

No chemical reaction or adhesion with fired ceramic components, ensuring the stability and consistency of electronic ceramic product performance, and improving the qualification rate of fired products;

5. Cerium zirconium composite oxide

The demand for automotive exhaust purification catalysts has gradually increased in recent years with the continuous upgrading of automotive exhaust emission regulations and related standards;

6. Mold coating

The superior properties of zirconia, such as high strength, thermal shock resistance, and low expansion coefficient, can ensure the precision of castings used for the inner layer of titanium alloy casting components, turbine engine slurry, and golf ball heads;

7. Nuclear grade zirconium metal

Nuclear fuel elements are the core components of nuclear reactors, and nuclear grade metal zirconium, due to its excellent neutron physics, mechanical, and hydrochemical properties, has become a material for high-performance nuclear fuel element cladding.

2、 Advantages of fused zirconia

1. Good color stability

Electromelted zirconia, due to its increased purity, is not easily reactive under high temperature conditions, does not emit gas, is corrosion-resistant, has low solubility in molten glaze, and has stable color.

2. Strong color rendering power

Add less to the glaze.

3. Good miscibility

Different colors of zirconium vanadium blue, zirconium praseodymium yellow, and zirconium iron red can be mixed in any ratio to prepare various rich and colorful mixed colors, further expanding their application range.

4. Pure color

Due to its high purity, it is not affected by the firing atmosphere, and the influence of the base glaze composition is relatively small. It has strong adaptability to glaze materials, high color saturation, and a bright color appearance.

5. Green and environmentally friendly materials

The use of fused zirconium raw materials to synthesize zirconium iron red is environmentally friendly, pollution-free, and pollution-free, providing a reference for the use of environmentally friendly materials in the production process of ceramic pigments.
