What is ternary piezoelectric ceramics?
2020 08/24
The gas element piezoelectric ceramic solid solution formed by three ARCl3 type compounds is a ceramic material of flying crystal phase. Compared with binary system piezoelectric ceramics such as lead complex acid lead acid (Ph2r03-P6`I'if )3), it has the characteristics of wider firing temperature range and low porosity (two in I'bGrT)3-PbTif); Binary system basis r= various combinations of the third component added by people, called "composite metal ion combination" 2. Commonly used ternary piezoelectric ceramics are: excellent lead magnesium oxide series ", two Ph}; lvlg] two }Ib?}) U3-y}P6T;Cl; one two Yb'C.rD3) ], lead sharp zincate [two F'ir( Zn 1}'_Vh}}) C7s- y Fh`I'iUs One two}'h2r( )3)], the mirror lead manganate series Ren two P6(1VInr,3N6}i;) D3-y f'h}'i03-x Ph2rDs 1[.Silver lead antimonate series [xPh[ 5hlra}6, two)f}3-v P6Gr03)" lead manganese antimonate l}r.[xFb( Mn: two Sb2 move 03-y Y6TiD3 one two F62rD3 ); etc. In addition to using lead-containing compounds as the third component, there are also non-lead compounds. There are many types of two- and ternary piezoelectric ceramics such as A+'B-5 or A"B"Cl Jing-. On the basis of the three components, the fourth or more APf l3} compounds are added to form quaternary or multi-component piezoelectric ceramics. Its use is very general. It can be used to make loudspeakers, filters, transformers, ultrasonic delay lines, high-power underwater acoustic emission and reception, high-voltage generating components, etc.
