  High-temperature zirconia materials, due to their comprehensive “thermal shock resistance,” “corrosion resistance,” “high-temperature strength” and “erosion resistance,” have become key materials for ensuring the safe, efficient, and continuous operation of modern steel continuous casting processes. In particular, their application in core components such as continuous casting nozzles, which control the flow of high-temperature melt, brings benefits such as improved production stability, reduced accident rates, and improved product quality.   Below are some product examples:   1.Sizing Nozzle: A sizing nozzle is a high-temperature structural ceramic functional device installed at the bottom of the continuous casting tundish. Its main function is to maintain a relatively constant static pressure of molten steel in the tundish. Molten steel flows into the crystallizer via the sizing nozzle. The crystallizer uses high-flow-rate water cooling to remove the heat released dur...

  Cameras rod components is very small and it was made by zirconia ceramic, the zirconia ceramic pin rods manufacturing process request strict quality control and advanced ceramic technology . Each rod is carefully produce to ensure precise dimensions and smooth surfaces. This attention to detail is essential for seamless integration into the camera’s design and for optimal performance.   Zirconia ceramics  pin rods are often used in camera applications due to their excellent properties, they can serve various functions, including acting as guiding rods, support structures, or wear-resistant components in mechanisms like lens adjustments or focusing systems.     Zirconia ceramic pin rods feature: · Coefficient of thermal expansion similar to iron · High strength&hardness · High fracture toughness · Wear resistance · Excellent thermal insulation · Very high resistance to crack propagation, high fracture toughness · Low thermal conductivity · Corrosion resista...

  Technical ceramics  generally have excellent corrosion resistance, this mainly depends on their chemical composition and microstructure. The chemical composition of ceramic determines the type and extent of its reaction with corrosive media. The microstructure, including grain size, porosity, microstructure, etc., also significantly affects the corrosion resistance of technical ceramics. So they are highly resistant to chemical attacks and do not easily react with aggressive substances. This property makes them suitable for various applications in corrosive environments, such as in the chemical industry, oil and gas industry, marine applications, and electric power generation. Also, technical ceramics have low porosity, high density, and excellent thermal stability, which enhance their corrosion resistance.    In addition to the characteristics of the material, we can also improve the corrosion resistance of the material in the following ways:   1. Surface tre...

The lattice of  zirconia ceramics   is stable at high temperatures, and the lattice phase is damaged once it reaches normal temperatures. Therefore, 94.8% of zirconia reaches a stable state at room temperature, and a 5.2% stabilizer must be added. The powder is dry-pressed and sintered at 1560 ℃, the hardness and toughness will exceed 99% alumina ceramics, and its wear resistance and impact resistance will exceed 99% alumina ceramics. If no stabilizer is added, the ceramic is easy to crack, so zirconia balls are used as abrasive materials because they have great hardness and toughness.

Zirconia is a very strong industrial ceramic with excellent properties in terms of hardness, fracture toughness and corrosion resistance; it solves the most common characteristic of ceramics-high brittleness. Its unique crack propagation resistance and high thermal expansion make it an excellent material for joining ceramics and metals such as steel. Due to the unique properties of zirconia, it is sometimes referred to as “ceramic steel”. Zirconia (ZrO2) Ceramics  have the highest toughness and strength at room temperature of all the advanced ceramic materials. At present, it has been widely used in grinding balls, dispersion and grinding media, nozzles, ball valve seats, zirconia molds, micro fan shafts, optical fiber pins, optical fiber sleeves, drawing dies and cutting tools, wear-resistant knives, and other room-temperature resistant Grinding parts and so on. Zirconia is widely used in the fields of the thermal barrier layer, catalyst body, medical treatment, health care, texti...

The core component inside an oxygen sensor is the zirconia ceramic heating element, which will heat the O2 concentration on each side, turn the O2 to the voltage signals and send to the ECU. Innovacera provides three types of oxygen sensor chip that can help to improve the performance of the oxygen sensor: 1. SWITCH TYPE OXYGEN SENSOR 2. WIDE BAND OXYGEN SENSOR 3. AIR-FUEL RATIO SENSOR Till now, those zirconia ceramic heating element has been used on the automotive such as TOYOTA, LEXUS, AUDI, Santana, Magotan, etc.

They as structural ceramics and functional ceramics apply in machinery, electronics, chemical industry, metallurgy, energy, aerospace and many other fields. But ceramics have an obvious disadvantage-fragility. The main reason is that the toughness of most ceramics is low, which leads to an increase in brittleness. There is a ceramic - zirconia with high toughness. It is formed by thousands of unit cells to form crystals. It then undergoes high-temperature phase transformation to form microcrystalline ceramics so that the ceramics have excellent wear resistance and drop resistance and high-temperature resistance. ZrO2 ceramic products are white. When the ceramic contains other impurities, the ceramic is grey or yellow. Commonly used moulding processes are injection and dry press. They are usually made into crucibles, mobile phon...
