Piezoresistor ceramic material and preparation method thereof
The invention discloses a piezoresistor ceramic material. The material is composed of the following components in percentage by mole: 0.2-8.0 mol% of Bi2O3, 0.1-8.0 mol% of Sb2O3, 0.2-8.0 mol% of Co3O4, 0.1-5.0 mol% of MnCO3, 0.1-2.0 mol% of B2O3, 0.1-4.0 mol% of Ni2O3, 0.001-0.003 mol% of Al(NO3)3.9H2O and the balance of ZnO, totaling 100 mol%. The invention also provides a preparation method ofthe piezoresistor ceramic material. According to the piezoresistor ceramic material provided by the invention, the transient overvoltage endurance capacity of a piezoresistor can be effectively improved, and the failure problem caused by transient overvoltage in an occasion where the piezoresistor is independently used is reduced. The manufacturing process is simple, obstacles in the use process of the piezoresistor are overcome, and the material has wide application prospects.
本发明公开了一种压敏电阻器陶瓷材料，由以下各组分按照摩尔百分比组成：BiO0.2～8.0mol％、SbO0.1～8.0mol％、CoO0.2～8.0mol％、MnCO0.1～5.0mol％、BO0.1～2.0mol％、NiO0.1～4.0mol％、Al(NO)·9HO 0.001～0.003mol％、ZnO补足至100mol％。本发明还提供上述压敏电阻器陶瓷材料的制备方法。本发明提出的压敏电阻陶瓷材料，能有效地提高压敏电阻器自身的暂态过电压耐受能力，减少在单独使用压敏电阻器的场合时因暂态过电压引起的失效问题。本发明制作工艺简单，克服了压敏电阻使用过程中的障碍，具有广泛的应用前景。
