Abstract
The invention discloses a piezoceramic material and a preparation method thereof. The piezoceramic material is characterized by being prepared from the following components in parts by weight: 65-73 parts of ZrO2, 15-23 parts of CaCO3, 8-15 parts of BaCO3, 8-12 parts of PVA (Polyvinyl Acetate), 5-8 parts of myristyl alcohol, 2-4 parts of SiC, 1-2 parts of BaTiO3 and 1-1.2 parts of graphene. The invention further provides the preparation method of the piezoceramic material. The method comprises the following steps: (1) weighing 65-73 parts of ZrO2, 15-23 parts of CaCO3, 8-15 parts of BaCO3, 2-4 parts of SiC, and 1-2 parts of BaTiO3; (2) adopting a wet ball-milling method to mix the components uniformly, heating the mixture at 750-810 DEG C, adding 8-12 parts of PVA, 5-8 parts of myristyl alcohol, and 1-1.2 parts of graphene to the mixture, and performing spray granulation and compression molding; (3) at last sintering the molded substance in an inertatmosphere at 1150-1200 DEG C for 2-3 hours to obtain the piezoceramic material.
Description
technical field [0001] The invention belongs to the field of ceramic materials, in particular to a piezoelectric ceramic material and a preparation method thereof. Background technique [0002] Ceramic materials are a class of inorganic non-metallic materials made of natural or synthetic compounds through shaping and high-temperature sintering. According to the use of ceramic materials, ceramic materials can be divided into ordinary ceramic materials and special ceramic materials. [0003] Ordinary ceramic materials are mainly made of feldspar, clay and quartz, which are typical silicate materials; while special ceramic materials are mainly made of high-purity artificially synthesized raw materials, which are formed and sintered by precise control technology, and generally have certain Special features to suit various needs. [0004] The main components of special ceramic materials are oxide ceramics, nitride ceramics, carbide ceramics, cermets, etc.; special ceramics have...
