High-Performance Technical Ceramics

Technical Ceramics represent high-performance oxide materials engineered specifically to survive operating environments where conventional metals, alloys, and polymers quickly fail.

Micro Engineering supplies custom technical ceramic spares manufactured in high-purity **Alumina ($Al_2O_3$)** and **Zirconia ($ZrO_2$)**. These materials are characterized by outstanding dielectric isolation, extreme high-temperature stability, complete chemical inertness, and exceptional wear resistance.

Perfect for electrical insulators in high-voltage panels, dosing pump plungers, sandblasting nozzles, and corrosive acid pumps.

Mechanical Properties

  • Material Grade: 99.5% Alumina / YSZ
  • Mohs Hardness: 9.0 (Alumina)
  • Max Temp: 1,600°C (Alumina)
  • Dielectric Strength: 18 – 20 KV/mm
  • Flexural Strength: 350 MPa

Features & Benefits

Providing total reliability in high-voltage and high-temperature systems.

High Dielectric Strength

Providing high-grade electrical isolation and leakage path resistance, making it perfect for custom insulating sleeves and bushings.

Severe Temperature Limits

Retains mechanical strength and dimensional structure up to 1,600°C. Resists sagging and thermal creep in high-heat kilns.

Complete Corrosion Immunity

Unlike metals, oxide ceramics are fully oxidized and completely inert to caustic chemicals, strong acids, solvents, and salt spray.

Exceptional Hardness & Wear

Alumina ranks 9 Mohs on the hardness scale. Protects sliding assemblies against scoring from high-velocity particulates and slurry flow.

Engineering & Performance Factors

Comparing technical profiles of Alumina ($Al_2O_3$) and Zirconia ($ZrO_2$).

Density (g/cm³) 3.90 – 3.95 6.00 – 6.05
Mohs Hardness 9.0 8.5
Max Operating Temp 1,600°C 1,150°C
Fracture Toughness Moderate (Brittle, typical ceramics) Excellent (Very high, "ceramic steel")
Best Used For Electrical insulation bushings, thermocouple protector tubes, high-temp lab crucibles, acid seals. Heavy load bearing pump plungers, wear sleeves, industrial slicing blades, wire guides.

Typical Applications

High-grade ceramic components installed across vital industrial setups.

01

High-Voltage Insulators

Installed inside high-voltage electrical switchgear, transformers, and heating element guide insulators.

02

Pump Pistons & Plungers

Zirconia plungers are utilized in chemical dosing pumps and high-pressure washers, reducing wear on seal packings.

03

Wire Drawing Pulley Guides

Highly polished alumina guides prevent metal wire abrasion during high-speed copper and steel drawing operations.

04

Crucibles & Furnace Parts

Refractory alumina tubes, trays, and crucibles are used to melt high-purity alloys inside induction furnaces.
