Fused Zirconium Dioxide/Yttria Stabilized Zirconium/Acetylene Carbon Black

Structrual Ceramic

Structrual Ceramic

Because ZrO2 structure is special crystal structure, to stabilize the crystal ZrO2 structure, usually add some ionic radius stabilizers similar Zr, such as Y2O3, CaO, MgO style, CeO2, Sc2O3, and etc in the system of ZrO2. Their solubility is very big in the ZrO2, easy to form solid solution, can change the crystal ZrO2 structure, and made ZrO2 form metastable tetragonal phase, tetragonal phase or cubic phase. After stabilized ZrO2 structure is no reversible transformation and volume effect, partially stabilized zirconium has the character of toughening and it is an important materials of the structure ceramic.

Structural ceramics is a kind of ceramic materials which has the special mechanical property and some part of thermology and chemical capability. In fact, ZrO2 toughened ceramic is partially stabilized ZrO2 composed of a variety of stabilizer. And its assured crystal structure is polycrystalline structure which takes tetragonal phase as the main body and includes cubic phase and monoclinic phase. Therefore, the application range of structural ceramics is very wide, it is considered to be one of the most promising new type structure material.

Jiaozuo Chengyuan Trading Co., Ltd., a trusted supplier of yttria stabilized zirconium, provides cheap raw material for structural ceramics. Buy high quality raw material from us!


Applications:

1. Structural ceramics are used in parts of engine and internal combustion engine, ceramic bearings, roller, pry bar, ceramic valve and ceramic plunger, etc

Because partial stabilized zirconia has good properties of ceramic, such as superior strength and toughness, low thermal conductivity, low elastic modulus, good thermal shock, and high working temperature is 1100℃, it is used in the manufacture of engine parts and internal combustion engine parts. With small volume, light weight, high thermal efficiency, toughness zirconium oxide can also be used for lots of parts, for instance, cylinder liner, piston, ceramic valve guide, intake and exhaust valve seat, ceramic bearings, 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

2.Grinding media and grinding tool

Be used in ball media, ball mill, 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.

3.Ceramic knives, 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 zirconia 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.

4.Biological ceramic: 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, zirconia teeth, artificial bone, imitation jewelry, zirconia tooth cap and etc.

5.Be used in bulletproof armor in the military
