3%mol yttrium stabilized zirconia we supplied adopts advanced chemically coprecipitation method to produce. Yttrium stabilized zirconia is a kind of non-toxic, tasteless, white Ysz powder, and have enough stability in alkali solution and lots of acid solution, except hot concentrated H2S04, HF and H3P04. Yttrium stabilized zirconium has superior thermal shock resistance, high temperature resistance, good chemical stability features, and Ysz thermal conductivity is lowest but thermal expansion coefficient is close to metal materials.3% mol Yttria Stabilized compound other materials such as Al2O3 and SiO2, which could greatly improve the performance of material parameters, the fracture toughness, flexural strength, etc. In order to improve the performance of ceramics, 3mol Yttria Stabilized is sprayed to granulated by advanced high-speed centrifugal scatter method, the advantages of product are good dispersion and liquidity, very small microscopic grains, uniform the grain size distribution, no agglomeration, is good for molding and pressing of the ceramic, increase the density of ceramics. So after through dry pressing molding and isostatic pressing molding of ceramic green body is with high density and strength, smooth surface, uniform inside and outside, not easy break and low porosity.

1.Structural ceramics or toughness ceramics
Yttria stabilized can be used in high strength, high toughness and wear-resistant products, such as grinding medium, lining and wear parts of grinding machine, cutting tools, wire-drawing die, hot extrusion die; because of good strength and toughness, low thermal conductivity, low elastic modulus, high thermal shock, and 1100℃ high working temperature, used in parts of engine and internal combustion engine. For example, ceramic bearings, roller, pry bar, ceramic valve and injector, and etc. In addition, toughness zirconium oxide with small volume, light weight, high thermal efficiency, it also can be used to produce lots of parts, for instance, cylinder liner, piston, ceramic valve guide, intake and exhaust valve seat, ceramic plunger, lifter, cam, cam follower and piston ring. Moreover, Yttria stabilized still use to make the computer drive components, seal, cooling blade of aircraft engine
2.Grinding media, grinding tool and grinding machine parts
Yttrium stabilized zirconium is used in ball media, ball mill, interior lining of ball mill and wear-resisting parts. The consumption of toughness ceramic accounts for more than half in the field of grinding media in China, but zirconium oxide ball accounts for the vast majority in grinding media.
3.Ceramic knives and wear resistance and corrosion resistance mechanical parts
Toughness zirconia ceramics used to make ceramic knives, scissors, screwdriver, hammer, saws, an ax, high temperature sealing washer, etc. The zirconium ceramic knives are more suitable for cutting raw food and cooked food. As well as to be used in avoiding magnetic watch case, corrosion resistance parts and other instrument parts.
Because the zirconium oxide has high hardness, no magnetic, also won't rusty, it applies in nonmagnetic material products such as used for medical scalpel, artificial joints, zirconia teeth, artificial bone, imitation jewelry, zirconia tooth cap and etc.
5.Fiber optical connectors
The physical properties of zirconium dioxide is similar to fiber optical material. Yttrium stabilized zirconium oxide can effectively match fiber optical with the pin, as well as the mechanical properties of zirconium ceramics is high strength, good toughness, corrosion resistance, wear resistance and physical properties of ultrafine sintering grain, yttrium stabilized fiber can satisfy the requirement of the complicated working condition, and has extremely low wear rate in the process of repeatedly plug and pull out.
6.Functional ceramics and electronic ceramics
Used in produce insulating ceramic materials, integrated circuit substrate, high frequency insulating ceramics and etc. Ultrasonic transducer, filter, piezoelectric ignition, piezoelectric motor, resonators, piezoelectric element, oxygen sensitive resistor, high-capacity capacitor, etc
The main steps of ysz powder by chemically coprecipitation method: mixing ZrOCl2 with YCl3 solution, then through coprecipitation, water washing, alcohol aging, low temperature drying, calcination, ball mill, airflow crushing, and sieving. Generally speaking, in order to improve the performance of ceramics, yttrium stabilized zirconia powder will be granulated by high-speed centrifugal spray.
