The material of zirconia ceramic rod is the special one in technical ceramic family. Traditional technical ceramics generally give people the impression of being FRAGILE, but zirconia ceramic has broken this stereotyped concept. After the continuous improvement of the purity and the manufacturing process, it not only improves its toughness, but also uses the ceramic itself to perfectly resist heat, corrosion and wear, low thermal expansion coefficient and high rigidity. Zirconia rods have now been used to replace various alloy materials in various industries.

The basic manufacturing process of ceramics is mainly composed of raw material adjustment → forming → sintering → processing, assembly → inspection, but in response to changes in product characteristics, the process needs to be matched with the characteristics of the raw materials to obtain the desired final product. The characteristics of the raw materials include major variables such as particle diameter, particle shape, flow and filling characteristics, and chemical composition. These variables will directly affect the ceramic forming and sintering process and the characteristics of the zirconium oxide rod. Therefore, fully grasping these variables can control the entire process smoothly.

First, the most economical way to produce zirconia powder is to directly mix zirconium ore (ZrSiO4) with carbon, decompose SiO2 by arc, and then obtain Zr O2 from the generated ZrC by electrofusion method. The purity and particle size of zirconia obtained by this method are both It is poor and can only be used as refractory material. For zirconia pins and zirconia ceramic pin to achieve the desired high toughness and high bending strength, the raw material powder must have a high degree of sinterability and a sub-micron size. Therefore, in order to meet these conditions, the zirconia raw material needs to be purified. The method is usually The compound is refined by chemical methods such as distillation and recrystallization, and then purified by physical methods such as vacuum metallurgy, distillation, thermal decomposition, and extraction. The toughness of the traditional stabilized zirconia ceramic produced by the above method is still not enough. The process requires the addition of stable substances such as CaO, MgO, Y2O3 or Al2O3. After homogenization at high temperature, the aging treatment is carried out at an appropriate cooling rate to obtain various parts. Stabilized zirconia ceramics (PSZ), its toughness is several times higher than traditional pure zirconia.
