Rhombic zirconia ceramic gasket

Are you looking for a sealing or spacer material that can withstand extreme environments and has a long service life?
Has your equipment experienced frequent downtime and increased maintenance costs due to gasket wear, corrosion or insulation failure?
Do you need a reliable component that is highly hard, chemically inert and can be precisely machined into complex shapes?
If any of the above are problems you are facing, then the rhombic zirconia ceramic gasket is the innovative solution tailored for you. It not only effectively solves the sealing and supporting problems under high-temperature, strong-corrosion and high-maintenance conditions, but also significantly improves the operational stability and production efficiency of the equipment.

The rhombic zirconia ceramic gasket is a special ceramic precision component made from high-purity zirconia (ZrO₂) powder through advanced molding and high-temperature sintering processes. Its distinctive “rhombic” design not only refers to the appearance but also represents the excellent mechanical distribution characteristics of its structure, which can effectively disperse stress and prevent edge cracking.

Application fields:

• Semiconductor and electronics industry: As insulators and sealing gaskets inside wafer processing and etching equipment, resistant to plasma corrosion, ensuring high cleanliness.
• Chemical industry and pump valve systems: Used for mechanical sealing rings and valve sealing surfaces in harsh chemical media, resisting comprehensive erosion by acids, alkalis, and salts.
• High-end machinery: As wear-resistant gaskets and spacer blocks in bearings, guides, and measuring instruments, maintaining long-term operational accuracy.
• New energy and research: Applied in fuel cell stacks, high-temperature reaction devices, etc., providing stable high-temperature insulation and gas sealing.

Why choose zirconia material?

1. Outstanding wear resistance and long service life: The Vickers hardness of zirconia ceramics is above HV 1250, which is far superior to that of most metals and engineering plastics. This significantly reduces the frequency of replacement and maintenance costs.
2. Excellent corrosion resistance and chemical stability: It has excellent inertness to most acids, bases, and molten metals, and can work stably in highly corrosive environments, avoiding contamination or failure caused by material deterioration.
3. Excellent high-temperature performance: The working temperature it can withstand is above 800℃, and its thermal expansion coefficient is close to that of metals, making it easy to cooperate with metal components and having good thermal shock resistance.
4. High hardness and low friction coefficient: The surface is smooth, the friction coefficient is low, reducing power loss, and avoiding wear on the mating parts.
5. Excellent insulation performance: High resistivity, maintaining excellent electrical insulation even under high temperature and high pressure, ensuring the electrical safety of the equipment.

The specific problems we can solve

• Address the issue of frequent replacements: Replace the worn-out rubber, graphite or ordinary metal gaskets with new ones, which can increase the component lifespan by several times to dozens of times.
• Eliminate the risk of medium leakage: In high-pressure and corrosive fluid transportation systems, provide reliable sealing to ensure production safety and environmental safety.
• Enhance equipment accuracy and reliability: In precision machinery, provide stable-sized, non-magnetic, and anti-rheological support and intervals to ensure long-term accuracy.
• Overcome extreme working condition challenges: In complex environments with high temperatures, severe wear, and strong corrosion, provide a “one-stop” material solution.

Customer Application Cases (Anonymized)

• Case A: An international semiconductor equipment manufacturer
  Customized thousands of rhombic zirconia ceramic gaskets for its dry etching machines, used to fix and insulate internal electrodes. Successfully solved the problem of rapid corrosion and particle contamination of the original aluminum gaskets in the plasma environment, extending the maintenance cycle from 3 months to over 2 years, significantly improving the equipment’s operational rate for the customer.
• Case B: A leading domestic chemical pump enterprise
  Used our custom rhombic zirconia sealing gaskets instead of the original polytetrafluoroethylene (PTFE) gaskets in its magnetic pumps for transporting concentrated sulfuric acid. Completely solved the stubborn problem of PTFE’s easy cold flow deformation leading to leakage under high pressure. The equipment has been running without faults for over 18 months, avoiding potential safety accidents and downtime losses for the customer.
• Case C: A high-end bearing research and development laboratory
  Used our ultra-flat rhombic zirconia gaskets as precise spacer plates in its high-speed bearing test bench. Its extremely low friction coefficient and nearly zero thermal expansion deformation helped the customer obtain more accurate and repeatable bearing performance test data, accelerating the development process of its new products.
