The main characteristics of zirconia industrial ceramic rods are high strength, high fracture toughness, high hardness and high density, stability, wear resistance, corrosion resistance, and high temperature resistance. So how should zirconia industrial ceramic rods be used correctly? Let me introduce it to you next.

1. After the zirconia industrial ceramic rod is heated in the air, a dense zirconia film is formed on the surface, which becomes an anti-oxidation protective film and increases the use time.

2. The greater the amount of current added to the zirconia industrial ceramic rod, the higher the surface temperature of the ceramic rod, and the shorter the use time of the blue zirconia industrial ceramic rod with the higher the use temperature. Therefore, after the furnace temperature exceeds 1600 ° C, the oxidation rate is accelerated., shorten the use time, and try not to let the surface temperature of the ceramic rod be too high during use.

3. During the use process, the resistance gradually increases due to the oxidation of the rod. In order to keep the furnace temperature normal, the use voltage should be increased. When the voltage is increased to the maximum limit of the transformer used and still cannot meet the requirements, the furnace can be stopped to change the wiring method of the rod and continue to use.

4. When the new furnace starts to send electricity, in order to prevent the rod from breaking, the voltage should be gradually increased. Generally, the starting voltage is 1/2 of the rated voltage. After everything is normal, the voltage should be gradually increased. For new furnaces or electric furnaces that have not been used for a long time, they should be baked before use. Use old rods or other heat sources as much as possible when baking.

5. Zirconia industrial ceramic rods are strictly prohibited from being overloaded. If the rod breaks for some reason or it is found that the rod has uneven heating, and the part is incandescent or dark red for a period of time, this means that the rod body is aging inconsistently, and the resistance difference between one section is too large., should stop the furnace for maintenance and replace the rod.

The above is how to use the zirconia industrial ceramic rod brought by Kezhong Ceramics correctly. Kezhong Ceramics is a manufacturer focusing on the production and processing of ceramics, focusing on the processing of alumina ceramic parts and zirconia ceramics. Ceramic products can be processed according to your needs.

Comparison of properties of zirconia and alumina

Zirconia ceramics are a material with high resistance to crack growth. It has a high coefficient of thermal expansion, so it is often used to make metallized ceramics. Zirconia is an excellent ceramic material with two outstanding properties of low thermal conductivity and high strength. It is widely used as a mold for wire forming, and can be used as an auxiliary material in the welding process. At the same time, it is often an ideal choice for insulating rings in high temperature use environments.

What are the mechanical properties of zirconia ceramics

Zirconia ceramic materials usually go through blank cutting, grinding, grinding and polishing to make the required parts. This process requires machining, and the machinability of zirconia ceramics includes cutting, grinding, grinding and polishing.

Characteristics and Application of High Purity Zirconia Beads

As the fineness requirements of materials become higher and higher, the use of sand mills is becoming more and more common, and there are more grinding media on the market, and zirconia beads are the leader. In the production of coatings, zirconia beads are required for coating sand grinding. The particle size of zirconia beads will become smaller after long-term grinding. The smaller particle size of zirconia beads will reduce the grinding efficiency, and new zirconia beads need to be replaced regularly to meet the process requirements.
