摘要：
Langasite (La3Ga5SiO14, LGS) and gallium orthophosphate (GaPO4) resonators exhibit piezoelectrically exited bulk acoustic waves at temperatures of up to at least 1400∘C and 900∘C, respectively. Their mass sensitivity at elevated temperatures has been found to be about as high as that of quartz at room temperature. Within its operation temperature range, GaPO4 shows significantly lower losses than LGS.
