Typical Applications of Alumina Ceramic Pump Core
Semiconductor Wet Processing Equipment
- Etchant Transfer Pump: Laminar/turbulent flow control; flow fluctuation < ±1.5%; HF/HNO₃ resistant; ion contamination < 0.1 ppb.
- CMP Slurry Circulation Pump: Nano‑finished surface (Ra ≤ 0.05 μm); resists abrasive particles; service life > 20,000 hours.
New Energy Sector
- Fuel Cell Hydrogen Recirculation Pump: Zero hydrogen embrittlement; hydrogen permeability < 1×10⁻¹⁰ mol/(m²·s·Pa); optional Pt/Ru conductive coating.
- Sodium-Sulfur Battery Molten Salt Pump: Resists 400°C molten sulfur & liquid sodium; thermal shock resistant (ΔT=800°C→room temp, 50 cycles no cracking).
Special Industrial Systems
- High-Temperature Molten Salt Heat Transfer Pump: Resists 600°C nitrate/chloride molten salt; low thermal expansion (6.5×10⁻⁶/°C).
- Nuclear Waste Treatment Pump: Gamma radiation resistant (>10⁶ Gy); zero radioactive adsorption; decontamination factor > 10³.
