Zirconia ceramic parts have the characteristics of high strength, high hardness, low density, low coefficient of expansion, wear resistance, heat insulation, corrosion resistance, good chemical stability, and excellent electrothermal performance. New materials in chemical, machinery manufacturing and other fields.

However, because zirconia ceramic parts have the characteristics of high brittleness, low fracture toughness, and the elastic limit and strength of the material are very close, the processing is very difficult, and the slightly improper processing technology will cause the destruction of the surface layer structure of the workpiece, which is difficult to achieve. The processing of high precision, high efficiency and high reliability limits the further expansion of the application range of zirconia ceramic materials.

In order to meet the growing demand for brittle material products such as fine ceramics, optical glass, crystals, quartz, silicon wafers and germanium wafers due to the development of science and technology in recent years, on the basis of the current relatively mature zirconia ceramic parts processing technology, further research and development High-precision, high-efficiency and high-surface integrity machining processes are particularly urgent.

Because zirconia ceramic parts have high temperature resistance, chemical corrosion resistance, oxidation resistance, wear resistance, large coefficient of thermal expansion, small specific heat and thermal conductivity, and toughening properties after stabilization, the stability of zirconia ceramic parts has become an important material that cannot be ignored in the refractory industry and special ceramics.

The foam ceramics produced can be used for the filtration of superalloy, and the foam ceramics are used in the filtration of molten steel continuous casting and have achieved good purification effect, effectively removing non-metallic inclusions.

It can be used as a casting port for special refractories, as a crucible for melting precious metals such as platinum, palladium, rhodium, etc., and can also be used as a lining for steel drums and flow steel troughs, and as an injection brick (fixed-diameter nozzle, immersion nozzle) in continuous steel casting., long nozzle slag line material and zirconium ring in sliding plate) to meet the requirements of the development of iron and steel smelting technology.

Due to the high hardness of zirconia ceramic parts, they can be made into cold forming tools, shaping dies, wire drawing dies, cutting tools, grinding media, fish knives, scissors, golf club heads, etc. High strength and good toughness, so they can be used to manufacture engine components, such as push rods, connecting rods, bearing cylinder liners, piston caps, etc. It also has semiconductivity and sensitive properties, and can be made into solid electrolyte diaphragms for high-temperature fuel cells, detection heads for oxygen measurement in molten steel, and oxygen concentration sensors in gases.

Comparison of properties of zirconia and alumina

Zirconia ceramics are a material with high resistance to crack growth. It has a high coefficient of thermal expansion, so it is often used to make metallized ceramics. Zirconia is an excellent ceramic material with two outstanding properties of low thermal conductivity and high strength. It is widely used as a mold for wire forming, and can be used as an auxiliary material in the welding process. At the same time, it is often an ideal choice for insulating rings in high temperature use environments.

What are the mechanical properties of zirconia ceramics

Zirconia ceramic materials usually go through blank cutting, grinding, grinding and polishing to make the required parts. This process requires machining, and the machinability of zirconia ceramics includes cutting, grinding, grinding and polishing.

Characteristics and Application of High Purity Zirconia Beads

As the fineness requirements of materials become higher and higher, the use of sand mills is becoming more and more common, and there are more grinding media on the market, and zirconia beads are the leader. In the production of coatings, zirconia beads are required for coating sand grinding. The particle size of zirconia beads will become smaller after long-term grinding. The smaller particle size of zirconia beads will reduce the grinding efficiency, and new zirconia beads need to be replaced regularly to meet the process requirements.
