Specifications of High Quality High Purity ZrO2 / Zirconia / Zirconium Oxide Ceramic Tubes

High-quality high-purity ZrO2/zirconia/zirconium oxide ceramic tubes are engineered for demanding industrial applications. The material composition is over 99% ZrO2. This ensures excellent chemical stability and mechanical strength. The ceramic tubes are made using advanced sintering techniques. These techniques guarantee uniform density and minimal porosity. The result is a product resistant to wear, corrosion, and high temperatures.

The tubes have a density of 6.0 g/cm³ or higher. This high density contributes to their durability and structural integrity. They operate effectively in temperatures up to 1600°C. The thermal expansion coefficient is low. This reduces the risk of cracking under rapid temperature changes. The material’s thermal conductivity is also low. This makes it ideal for insulation in high-heat environments.

Standard outer diameters range from 5 mm to 150 mm. Wall thicknesses vary between 1 mm and 20 mm. Custom sizes are available. Lengths can be tailored to meet specific requirements. Surface finishes are smooth, with roughness values (Ra) below 0.4 micrometers. This precision minimizes friction and wear in applications like bearings or seals.

The ceramic tubes exhibit exceptional resistance to acids, alkalis, and molten metals. They perform reliably in harsh chemical environments. Electrical insulation properties are outstanding. Volume resistivity exceeds 10^12 Ω·cm at room temperature. This makes them suitable for electronic and semiconductor applications.

Mechanical strength is a key feature. Flexural strength exceeds 800 MPa. Hardness is above 1200 HV. These properties ensure longevity under heavy loads or abrasive conditions. The material’s fracture toughness is higher than other ceramics. This reduces brittleness and improves reliability.

Applications include thermocouple protection, furnace linings, and laboratory equipment. They are used in aerospace, medical devices, and chemical processing. The tubes are compatible with vacuum systems. They maintain performance in oxidizing or reducing atmospheres.

Quality control involves strict testing. X-ray diffraction (XRD) ensures phase purity. Scanning electron microscopy (SEM) checks microstructure consistency. Each batch undergoes dimensional, density, and hardness verification. This guarantees compliance with industry standards.

Applications of High Quality High Purity ZrO2 / Zirconia / Zirconium Oxide Ceramic Tubes

High-quality high-purity ZrO2 (zirconia or zirconium oxide) ceramic tubes are widely used in industries requiring materials that excel in extreme conditions. These tubes are known for their heat resistance, chemical stability, and mechanical strength. They perform reliably in high-temperature environments, making them ideal for industrial furnaces, kilns, and thermal processing equipment. Their ability to withstand temperatures over 2000°C without degrading ensures long service life in demanding applications.

In metallurgical processes, zirconia ceramic tubes serve as crucibles or protective sheaths for thermocouples. They protect sensors from molten metals, corrosive slags, and aggressive atmospheres. This ensures accurate temperature measurements and reduces equipment failure. The material’s low thermal conductivity also improves energy efficiency by minimizing heat loss.

The aerospace and energy sectors use these tubes in oxygen sensors and fuel cell components. Zirconia’s ionic conductivity at high temperatures enables precise monitoring of oxygen levels in exhaust systems. This supports emission control and combustion efficiency. In solid oxide fuel cells, zirconia tubes act as electrolytes, facilitating ion transfer while maintaining structural integrity under thermal stress.

Semiconductor manufacturing relies on high-purity zirconia tubes for handling corrosive gases and high-temperature processes. Their resistance to chemical erosion and thermal shock ensures contamination-free environments. This is critical for producing high-performance electronic components.

Medical applications include use in dental implants and surgical tools. Zirconia’s biocompatibility and resistance to wear make it suitable for long-term implants. Its smooth surface inhibits bacterial growth, reducing infection risks.

The chemical industry uses zirconia tubes in reactors and pumps for processing aggressive substances. The material’s inertness prevents reactions with acids, alkalis, and organic solvents. This extends equipment lifespan and maintains product purity.

Zirconia ceramic tubes also serve in research and development. They are used in lab equipment for material testing, catalysis studies, and high-temperature experiments. Their stability under variable conditions supports accurate data collection.

Customizable in size and shape, these tubes meet specific operational needs. Advanced manufacturing techniques ensure precise dimensions and consistent quality. This adaptability makes them valuable across diverse fields.
