On the Piezoelectric Properties of Tourmaline

Physics, 1933
Oscillating piezoelectric plates of different frequencies have been made from California and South African Tourmaline. These plates have a frequency response of approximately 3770 kc per millimeter of thickness. The temperature coefficient for both specimens was found to be negative and is about 35.5 parts per million per degree centigrade for the ...
