buy stabilized zirconia, yttrium stabilized zirconia cheap price, zirconia yttria for sale

Yttrium stabilized zirconium is a kind of non-toxic, tasteless, white powder. Yttrium stabilized zirconia has enough stability in alkali solution and lots of acid solution, except hot concentrated H2S04, HF and H3P04. It enjoys excellent properties of ceramic, such as strong thermal shock resistance, high temperature resistance and good chemical stability. Yttrium stabilized zirconia compound other materials (Al2O3, SiO2) which could greatly improve the performance of material parameters, the fracture toughness, flexural strength, and etc. Make high-tech composite materials with high temperature resistance, corrosion resistance, wear resistance and other good characteristics. Meanwhile, under the certain conditions, the composite materials can display the electric, magnetic, optical, acoustic and other special functions. The heat insulating and high temperature of ZrO2 composite materials is the best in a variety of metal oxide ceramic materials. Stabilized zirconia is an important component of senior ceramic pigment and glaze, it is suitable to be made into ceramic coating and high-temperature refractory products. Zirconia Yttria is an important kind of Zro2 structure ceramic materials, with the phase transformation toughening properties, good mechanical properties, high fracture toughness and bending strength, have the lowest thermal conductivity but thermal expansion coefficient is close to metal materials. Stabilized zirconia also is a wonderful material to be made into solid electrolyte, also can be used for SOFC electrolyte and high-temperature heater. Stabilized zirconia is widely used in electronic ceramics, structural ceramics, biological ceramics, high-grade refractory materials, piezoelectric element, radio components, optical lenses and other industries.

Yttrium stabilized zirconia can be used in high strength, high toughness and wear-resistant products, such as grinding media, lining and wear parts of grinding machine, cutting tools, wire-drawing die, hot extrusion die; because zirconia Yttria products with 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, zirconia Yttria also can be used to produce lots of parts, for instance, cylinder liner, piston, valve guide, intake and exhaust valve seat, lifter, cam, cam follower and piston ring. Moreover, yttrium stabilized zirconium still use to make the computer drive components, seal, cooling blade of aircraft engine

Be used in ball mill, ball media, interior lining of ball mill and wear-resisting parts and grinding machine parts. The consumption of toughness ceramic accounts for more than half in the field of grinding media in China, but zirconium oxide ball media accounts for the vast majority in grinding media.

The physical properties of zirconium dioxide is similar to fiber optical material. Yttrium stabilized zirconia 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, stabilized zirconia fiber can satisfy the requirement of the complicated working condition, and it has extremely low wear rate in the process of repeatedly plug and pull out.

Because the stabilized zirconia 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.

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.

Stabilized zirconia is 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.

Because Yttrium stabilized zirconia has a high ionic conduction under high temperature, cubic stability ZrO2 is widely used in solid electrolyte of solid oxide fuel cell (SOFC) and oxygen sensor. Zirconium oxide solid electrolyte is the core component of the solid oxide fuel cell (SOFC), its ionic conductivity largely determines the output power of SOFC and current density.

The main steps of yttrium stabilized zirconia dioxide 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.
