Black zirconia ceramic is a partially stabilized zirconium oxide engineered to deliver high strength and toughness in demanding industrial environments. The material also offers superior surface stability and dimensional control for tight-tolerance integration.

Black Zirconia Ceramic Benefits

  • High fracture toughness prevents failure in rotary shaft and pump seal applications.
  • The black color ensures visual contrast in automated systems for detection and alignment.
  • Chemically inert surface – withstands acids, alkalis, and oxidizing environments.
  • Low coefficient of thermal expansion – ideal for thermal cycling devices.
  • Electrically insulating and corrosion-resistant – suitable for sensor, aerospace, and lab applications.

Black zirconia ceramics Applications

  1. Electrical Tool Assembly: Used in electric motor insulation sleeves, rotary shaft bushings, or torque-transmitting elements with a mirror finish.
  2. Automated Dispensing Systems: Used as ceramic plungers in precision liquid dosing, due to high wear durability and low pore rates.
  3. Metallurgical Sampling and Furnace Supports: In high-temp, atmosphere-controlled ovens, black zirconia rings and supports ensure dimensional stability.
  4. Instrumentation: Laboratory instruments utilize black zirconia nozzles and connectors for chemical compatibility and the exclusion of trace detection in spectroscopy.

Black zirconia ceramics Usage Instructions

Usage:

  • Always ensure the component interfaces with metal or plastic elements using soft fixation; avoid rigidity that risks stress cracking.
  • Compatible with high-speed rotating systems below 6000 RPM
  • Max working temperature up to 1100°C in oxidizing atmosphere

Storage:

  • Store in dry conditions, ideally in original PE foam compartments.
  • Avoid extended exposure to UV light or alkaline air to protect surface integrity.

Cleaning:

  • Use ethanol or pH-neutral ultrasonic cleaning
  • Avoid hydrofluoric acid or fluorine salt mixtures

Common mistakes to avoid:

  • Excess torque during press fit assembly
  • Using metal screw fasteners on unstabilized holes
  • Operating near plasma arc or RF fields – black zirconia may heat due to dielectric loss
  1. Q: What types of black zirconia ceramics do you offer?
    A: We offer bushings, shafts, rings, plungers, nozzles, and discs with straight, stepped, or flanged geometry.
  2. Q: Can I use black zirconia in environments with corrosive fluids?
    A: Yes. It has strong chemical resistance to acids, alkalis, and salt solutions.
  3. Q: Is this material magnetically active?
    A: No. Black zirconia is completely non-magnetic and suitable for MR-safe applications.
  4. Q: How is it different from white zirconia?
    A: Black zirconia has similar mechanical properties but offers additional light absorption, surface readability, and visual traceability.
  5. Q: Are these items compatible with electrical insulation applications?
    A: Yes. Dielectric strength >10 kV/mm with volume resistivity >10^12 Ω·cm.
