Mechanical-acoustic study of electroporcelain mixture made under different compression pressures

Popis výsledku v původním jazyce

This paper presents mechanical-acoustic study of samples made from electroporcelain mixture (type C 130) under five different compression pressures from 70 MPa up to 110 MPa. The samples were studied using the impulse excitation technique, thermodilatometry, thermogravimetry, and acoustic emission in the temperature interval from 1100 to 50 degrees C. X-ray powder diffraction was used for the determination of crystalline phases. Microstructure observations using scanning electron microscopy revealed small differences between compression pressures 70 MPa and 110 MPa. The results of impulse excitation technique show that using a higher compression pressure an increase in Young&apos;s modulus is observed. The values of Young&apos;s modulus after cooling to room temperature reach 18.4 GPa, 19.5 GPa, 19.7 GPa, 19.9 GPa, and 20.1 GPa for the compression pressure of 70 MPa, 80 MPa, 90 MPa, 100 MPa, and 110 MPa, respectively. The results also show that the acoustic emission activity starts at solidification of the glassy phase in the temperature interval of 800-700 degrees C.
