SINTYRON High Quality Finish Machining Zirconia Ceramic Rod High Temperature Resistance Zirconia Ceramic Rod

Key Properties and Advantages

1. Exceptional Strength & Fracture Toughness: This is the standout feature of zirconia. Yttria-Stabilized Tetragonal Zirconia
   Polycrystals (Y-TZP) undergo transformation toughening. When stress is applied, a microscopic phase change around a crack
   tip creates compressive stresses that inhibit crack propagation. This gives zirconia rods remarkable resistance to chipping, breaking,
   and impact, making them far less brittle than alumina ceramics.

2. High Hardness and Wear Resistance: With a Vickers hardness of ~1200-1300 HV and a Mohs hardness of ~8.5, zirconia rods are
   extremely resistant to abrasion, erosion, and mechanical wear. They maintain a smooth surface even under constant friction.

3. Excellent Chemical Inertness & Corrosion Resistance: Zirconia is highly resistant to attack by most acids, alkalis, and solvents.
   It does not rust or corrode, making it ideal for harsh chemical environments and medical applications.

4. High Temperature Resistance: Zirconia has a very high melting point (~2,700°C / 4,890°F) and can operate effectively at elevated
   temperatures while maintaining its mechanical properties.

5. Low Thermal Conductivity: Zirconia is an excellent thermal insulator. This property is valuable in applications requiring thermal
   barrier protection or where heat transfer is undesirable.

6. Biocompatibility: Medical-grade yttria-stabilized zirconia is non-toxic, non-allergenic, and is approved for use in surgical implants
   and dental devices due to its excellent biocompatibility.

7. Electrical Insulation: Like most advanced ceramics, zirconia is an excellent electrical insulator.

Zirconia ceramic rods of Applications

• Precision Machinery and Automation:

  • Pins, Guides, and Rollers: Used in textile machinery, packaging equipment, and automated assembly lines for their wear
    resistance and smooth surface finish, ensuring long service life and reduced downtime.

  • Bearings and Bushings: Especially valuable in applications where lubrication is impossible (high-temperature, corrosive,
    or ultra-clean environments like food processing). Their high toughness allows for thinner designs compared to alumina bearings.

  • Fixture and Jig Pins: Used in precision welding and measurement fixtures for their dimensional stability, hardness, and electrical insulation.

• Medical and Dental Industry:

  • Surgical Instrument Components: Used in drills, probes, and cutting tools due to its hardness, corrosion resistance, and biocompatibility.

  • Dental Implant Abutments and Components: Its strength and tooth-like color make it an ideal material for restorative dentistry.

  • Orthopedic Trial Implants: Used as trial components in joint replacement surgeries.

• Measurement and Electronics:

  • Probe Styli for Coordinate Measuring Machines (CMM): Their low thermal expansion ensures dimensional stability for highly
    accurate measurements. Their hardness prevents wear from repeated contact.

  • Shafts for Sensors and Actuators: Used in sensitive equipment where non-magnetic, insulating, and wear-resistant properties are required.

• General Industrial:

  • Cutting Tools: Used as a substrate for cutting blades and tools.

  • Valve Components: Seats, stems, and balls in corrosive fluid handling systems.

  • Welding Nozzles: For their resistance to spatter and high temperatures.

Advantages and Limitations
Advantages:
Excellent overall mechanical properties (strength, toughness, and hardness).
Excellent chemical and high-temperature resistance.
Good thermal and electrical insulation.
Good biocompatibility.
Limitations:
Higher cost: Both the raw material and sintering process are more expensive than common ceramics like alumina.
Brittleness: Despite its high toughness among ceramics, it is still inherently brittle compared to metals and must be protected from severe impact and stress concentration.
Weight: High density (approximately 6 g/cm³), heavier than both alumina and silicon carbide.
