High hardness and high strength zirconia ceramic tube for industry
1. Description
Zirconia ceramic has the advantages of super hardness, high wear-resisting,good corrosion resistance and electric insulation,resistant acid-base,high intensity,thermostable,high temperature tolerance,good insulation,high strength,precision process,high mechanical strength,good chemical stability.Good smoothness, mechanical seal good, polishing surface and so on.
As a wear resistant material, ceramic is widely used in many fields, for example, mechanical, electron, petroleum, chemicals, space and textile. Our company import high quality ZrO2 and Al2O3 material from Japan, to make high precision ceramic components through hot pressing,dry pressing or injection molding and high sintering.
It is characterized by high hardness, insulation, wear resistant, high temperature resistant and thermal shock resistant. And all kinds of customized ceramic substrate are available in customized requirement.
Zirconia ceramic is the most mature of the engineering ceramics, offering excellent electrical
insulation properties together with high hardness and good wear resistance,but relatively low
strength and fracture toughness.Zirconia ceramics are generally white but may also be pink or
ivory.The color is derived from either the sintering additives or impurities in the raw materials.
1. High hardness.
2. High heat resistance : Zirconia ceramic has execellent themal stability,which means that it is
widely used in areas where resistance to high temperatures is essential.
3. Good wear resistance : Zirconia ceramic is the material of choice for wear parts.
4. High electrical resistivity : Zirconia is an electrically insulating material.
5. High corrosion resistance : It is insoluble in water and only slightly soluble in strong acid and
alkaline solutions. Good chemical stability of zirconia leads to high corrosion resistance.
2. Excellent features
Zirconia ceramic has the advantages of high glossiness, high heat resistance, good smoothness, good corrosion resistance, high wear-resisting, high intensity, precision process, polishing surface and so on. It widely used in a variety of mechanical equipments.
Unlike other ceramic materials, zirconia is a material with very high resistance to crack propagation. And its fine grain size enables excellent surface finishes and the ability to hold a sharp edge.
ZrO2 ceramics are used among other applications, as mobile phone shell, as zirconia diamonds, as materials for crowns and bridges in the dental industry, as insulating rings in thermal processes, and as oxygen measurement cells in lambda probes.
Industrial ZrO2 Ceramic is widely used in high-Pressure cleaning machines. sealing structure, auto mobile Industrial, oil drilling equipment, Insulation parts in electrical equipment , ceramic knife, ceramic hair clipper spare parts, with high density, bending strength and breaking tenacity.
