Zirconia Rod

Zirconia rods have superior toughness, high bending strength, excellent wear resistance and thermal insulation properties. Therefore, zirconia round rods are commonly utilized in place of metals in a variety of harsh environments.

Zirconia rods are typically formed via isostatic pressing, and a uniform, dense, and smooth ceramic layer can be generated under high pressure.

Benefits of Zirconia Rod

Corrosion Resistance

Because of the exceptional corrosion resistance, the zirconia rods are appropriate for use in seawater and some harsh corrosive situations.

Light Weight

Since zirconia rod has a lower density than steel and is lighter in weight, the centrifugal effect on the outer ring during high-speed rotation can be significantly reduced. This lowers the mechanical load and lengthens the service life.

Low Coefficient of Linear Expansion

Because the linear expansion coefficient of zirconia rod is very low, when utilized as a shaft rod with a constant gap between the shafts, the ceramic shaft can work in an environment with severe temperature variations.

Highest Fracture Toughness

Zirconia ceramics have exceptional strength and toughness due to phase transition toughening and microcrack toughening, and their fracture toughness is the highest among all ceramics. As a result, zirconia ceramics are more suited to being produced into slender ceramic rods or ceramic needles than alumina ceramics, and they are less prone to breaking during processing.

High Modulus of Elasticity

Since zirconia ceramics have a higher elasticity modulus than steel and are less likely to deform under stress, they are advantageous to increase working speed and achieve high precision. Overall, ceramic shafts outperform all-steel shafts in terms of performance and cost, which can significantly cut downtime and maintenance time, reduce scrap rates and the inventory of shaft spare parts.

High Surface Roughness

Zirconia rod has a surface roughness that is superior to that of alumina round rod. It has outstanding wear resistance, which is 266 times that of manganese steel, and it is non-toxic and anti-magnetic.

Characteristics of Zirconia Rods

Processing of Zirconia Rods

Unipretec can customize zirconia round rods, square rods, and special-shaped rods with a diameter of 1-50mm and a length of 10-600mm, and the products can also undergo processing like threading, slotting, drilling, polishing, and so forth, with dimensional tolerance control within ±0.002, and the roughness is 0.02.

Composition and Structure

Zirconium dioxide (ZrO2), a ceramic substance that under certain circumstances undergoes a phase transition (from monoclinic to tetragonal and cubic phases), makes up most of zirconia rods and greatly adds to their mechanical strength and toughness. Zirconia rods' fracture toughness is increased over conventional ceramics and they are able to withstand crack propagation thanks to this phase change toughening process.

Mechanical Properties

Among the main characteristics of zirconia rods is their remarkable mechanical qualities. Because of their great flexural strength and fracture toughness, they are very resistant to mechanical wear and fracture. This qualifies zirconia rods for uses like dental implants, wear-resistant components, and cutting tools where stress-resistance and durability are essential.

Thermal Stability

Best recognized for their outstanding thermal stability, zirconia rods can tolerate high temperatures without appreciably changing in size or losing their mechanical qualities. Because of their thermal resilience, they are appropriate for usage in high-temperature settings like furnace parts, kiln furniture, and thermal barrier coatings.

Applications in Medicine and Biocompatibility

Because of its remarkable biocompatibility and bioinert character, zirconia rods find extensive use in the medical and dentistry disciplines. They find wide application in prostheses and dental implants, where their biocompatibility guarantees less tissue irritation and long-term stability within the body. Because zirconia can osseointegrate—bond with bone tissue—it is the material of choice for dental implants, bridges, and crowns.

Industries-Wide Applications

Zirconia rods have wide range of uses in many different sectors:

Medical and Dental

Aesthetics, mechanical strength, and biocompatibility make them useful in dental implants, crowns, and prosthesis.

Industrial

Used when great mechanical strength and wear resistance are needed in cutting tools, bearings, valves, and wear-resistant components.

Automotive and aerospace

Use in high-temperature, mechanically stressed components including turbine blades, engine parts, and thermal barrier coatings.

Electronics

Excellent electrical insulating qualities make them useful in insulating components, oxygen sensors, and electronic circuit substrates.

Zirconia rods are extensively utilized in a variety of industries, including air conditioning motors, welding materials, high-pressure water pumps, high-pressure injection machines, high-pressure water cutting machines, lithium battery pumps, metering pumps, medical plunger pumps, and others.

Shaft Rod of Pump Equipment

Zirconia rod has a hardness similar to tungsten steel and is used as the shaft rods of various pump equipment. It has a service life that is more than ten times longer than that of conventional metal steel shafts, and belongs to highly wear-resistant material with extremely low wear at high speeds. It is utilized in the field of reciprocating plungers, with a reciprocating motion speed of more than 300 times per minute and a service life of 5-10 times that of a conventional metal plunger. Furthermore, zirconia ceramic material is resistant to deformation under high temperature and pressure.

Substitute for Traditional Stainless Steel Rods

Zirconia rod is comprised of a cylindrical ceramic rod body and a pointed tip at the front end, and can take the place of conventional stainless steel rods in the production of heat pipes. This ceramic rod is positioned in the center of the heat pipe and is fixed by the pointed tip at the front end. The new ceramic center rod does not require spraying and offers benefits such as easy plugging and unplugging, long service life, temperature resistance, no discoloration, and no deformation. Compared to stainless steel, it has extremely high cost performance.

Mechanical Motor Shaft Core and Rotor

Zirconia rods with high precision and roundness can be utilized as the shaft cores and rotors of mechanical motors, which have the benefits of excellent mechanical strength, and stable high-temperature performance, etc.

Other applications for zirconia round rods can be found in the fields of medicine, precision equipment, precision measurement and detection, and laser technology, etc., for example, they can be used in plunger rods, measuring rods, laser rods, laser range finders, laser guidance devices, gyroscopes, and so on.

Zirconia ceramics can take the place of metals to be used in a variety of harsh environments because they provide a series of excellent properties. They have the highest fracture toughness of all advanced ceramic materials, are difficult to break during processing and not easily deformed under stress. They are also light, non-toxic, and have a smooth surface.
