Abstract

Ca₂Al₂SiO₇ (CAS) bulk single crystals were grown by the Czochralski method. Material constants of the crystal were determined over the driving temperature range of a typical combustion pressure sensor. The electrical resistivity at 800°C was found to be of the order of 10⁸ Ωcm. We constructed a measurement system for the direct piezoelectric effect at high temperature, and characterized the crystals in a simulated engine cylinder combustion environment. Output charge signal against applied stress was detected at 700°C. These observations suggest that CAS crystals are superior candidate materials for high temperature for stress sensing.
