Abstract

The invention relates to gas ignition piezoelectric ceramics and a manufacture process thereof, which can be mainly applied to a lighter, a piezolighter, an automatic gas stove and a bullet exploding device. The gas ignition piezoelectric ceramics comprises the following main raw materials of lead oxide (PbO), zirconium dioxide (ZrO2), titanium dioxide (TiO2) and barium oxide (BaO) and trace adding raw materials of cerium oxide (CeO2), antimonous oxide (Sb2O3) and manganese dioxide (MnO2). The manufacture process comprises the steps of: weighting the raw materials; ball-grinding; filter-pressing to form blocks; roasting; roasting powder; pelleting; dry-pressing for forming; loading green blocks into a pot; sintering; polishing; silver-plating; silver electrode firing; and polarizing to obtain the gas ignition piezoelectric ceramics. According to the invention, the sintering temperature is reduced, the environment pollution caused by lead oxide volatilization is decreased, dielectric and piezoelectric coefficients are improved, and the energy consumption is reduced during the sintering.

Description

technical field [0001] The present invention relates to a piezoelectric ceramic composition and a manufacturing method of piezoelectric ceramics. Specifically, the present invention relates to gas ignition piezoelectric ceramics and a manufacturing process thereof; mainly used in lighters, piezoelectric igniters, automatic gas stoves, piezoelectric ignition Devices, shell detonators. Background technique [0002] Lead zirconate titanate ceramics (PZT) with piezoelectric properties is a material series widely used in electronic ceramics. It is mainly used in igniters to convert mechanical force into electric sparks to ignite combustible gases; the principle is to use piezoelectric The positive piezoelectric effect of ceramics, when the piezoelectric body is squeezed or impacted along the polarization direction, the ceramic rod is compressed and deformed, resulting in bound charges of opposite signs appearing on the surfaces of the two ends of the ceramic rod, and the generate...
