Thermal Management Applications
Heat sinks · power module heat dissipation · thermal conductive structural components
Technical ceramics combine high thermal conductivity with high-temperature resistance and chemical stability, which is why they show up in the parts of a vehicle's thermal system that have to survive sustained heat without drifting out of tolerance.
In water pumps, valves, and other wear-critical thermal components, ceramic parts keep their geometry and surface finish under long-term high-temperature operation — where metal or polymer equivalents would gradually wear, warp, or seize.
Why ceramics here:
→ Thermal conductivity without electrical conductivity
→ Stable dimensions from cold-start to sustained high heat
→ No creep or softening at engine and power-electronics operating temperatures
→ Chemically inert to coolants, oils and process fluids
We machine thermal-management ceramic parts to your drawing in the grade that fits your temperature and flow conditions.
Electrical Insulation & High-Voltage System Applications
Insulating ceramic structural components · electronic packaging · sleeves & supports
Automotive electrical insulation and high-voltage systems depend on materials that stay dielectrically reliable well beyond what most polymers can sustain. High-purity alumina and aluminum nitride hold dielectric strength in the 10–20 kV/mm range with volume resistivity above 10¹⁴ Ω·cm, and don't degrade the way plastic insulation can under heat and humidity.
In EV high-voltage systems, ceramic insulating sleeves, connector bodies, and sensor housings prevent electrical breakdown and leakage current in exactly the environments — high temperature, high humidity, corrosive exposure — where that risk is highest.
Typical high-voltage EV parts:
→ Battery pack insulating sleeves & standoffs
→ Connector and sensor housing insulators
→ Ceramic substrates & DBCs for power modules
→ Feedthrough insulators for sealed enclosures
Reference data: dielectric strength 10–20 kV/mm · volume resistivity >10¹⁴ Ω·cm (Al₂O₃, 25°C)
Structural Wear-Resistant & Low-Friction Applications
Bearings · sealing rings · valve seats · water pumps
Where automotive components face structural wear and low-friction demands at once, ceramics continue to outperform metal: high hardness, wear resistance, and a low coefficient of friction reduce both wear and energy loss under long-term, high-speed, high-load conditions.
Bearing components, sealing rings, sliding components, and pump bodies keep their dimensional accuracy and surface finish even in high-temperature, insufficiently lubricated, or corrosive environments — extending service life and cutting maintenance frequency.
Material fit for wear parts:
→ 3Y-TZP Zirconia: fracture toughness 8–10 MPa·m½, the highest of the standard technical ceramics
→ Silicon Nitride: high strength under cyclic mechanical load
→ Silicon Carbide: exceptional wear & corrosion resistance for pump and seal faces
We machine bearing, seal, and valve-seat geometries to your drawing and tolerance callouts.

Frequently Asked Questions
Can ceramic components handle EV battery pack thermal cycling?
Yes. Alumina and aluminum nitride components hold their dimensional and insulation properties through the repeated charge and discharge thermal cycling typical of EV battery packs, unlike polymer insulators that can soften or crack over time.
What ceramic materials are used for high-voltage EV insulation?
High-purity alumina and aluminum nitride are the standard choices, offering dielectric strength in the 10–20 kV/mm range and volume resistivity above 10¹⁴ Ω·cm, which keeps insulation performance stable under sustained high-voltage load.
Do you manufacture ceramic bearings for automotive applications?
Yes, in zirconia and silicon nitride. 3Y-TZP zirconia offers fracture toughness of 8–10 MPa·m½ — the highest of the standard technical ceramics — which is why it's specified for bearing and wear components under cyclic mechanical load.
Is Microns' manufacturing process certified?
Yes. Production runs under an ISO 9001:2015-certified quality management system, with raw material lots qualified by XRF composition analysis and finished parts inspected by CMM before shipment.
Can you supply automotive-grade ceramic substrates for power electronics?
Yes. We machine and metallize alumina and aluminum nitride substrates and DBCs for power module and sensor packaging, built to your drawing and material specification.
