More Details

  1. Why choose the OBP Series?
    Process Optimization:The ability to monitor real-time polarization current is crucial. Observing how the current changes over time under applied voltage and temperature helps researchers identify the ideal poling conditions (saturation point) for new or existing materials, avoiding under-poling or dielectric breakdown.
  2. Versatility: It supports both bulk ceramics and thin films, accommodating a wide range of R&D and production needs.
  3. Reliability and Safety: Integrated safety features like overcurrent protection, isolated shielding, and safety interlocks protect both the valuable samples and the operator, ensuring a safe and repeatable poling process.

FAQ

  • What is the primary purpose of the OBP Series polarization system?

    The OBP Series is specifically designed to perform high-voltage polarization (poling) of piezoelectric ceramics. By applying a high DC electric field (up to 10 kV or 30 kV) at controlled temperatures in a silicone oil bath, it effectively aligns the ferroelectric domains to maximize the material's piezoelectric activity (d33).
  • How does the oil bath temperature control benefit the poling process?

    The system features integrated oil bath heating up to 180°C with stable PID control. Poling at elevated temperatures lowers the coercive field of the ceramic, allowing domains to align more easily under lower voltages and reducing the risk of dielectric breakdown during high-voltage application.
  • What safety features are integrated into the OBP Series?

    Since the system operates at very high voltages (up to 30 kV), safety is paramount. The OBP Series features multiple layers of protection, including overcurrent detection (automatic cut-off under 1 mA), isolation shielding, and a safety interlock system that immediately shuts down high voltage if the chamber door or lid is opened.
