Description

一种用于氧化锌压敏电阻器制备的材料
技术领域
本发明涉及电子器件领域，尤其是涉及一种用于氧化锌压敏电阻器制备的材料。
背景技术
压敏电阻是一种限压型保护器件。利用压敏电阻的非线性特性，当过电压出现在压敏电阻的两极间，压敏电阻可以将电压钳位到一个相对固定的电压值，从而实现对后级电路的保护。近几年来，随着信息技术的迅速发展，电子设备的小型化、多功能化、高稳定性成为发展的必然趋势，作为保护半导体元件的压敏电阻也相应地向着轻薄、低压化、高可靠性方向发展。
而氧化锌压敏电阻器一直因其兼具工艺简单、成本低廉、使用方便等优点，获得了广泛应用。但现在由于汽车工业、通讯设备、铁路信号、微型电机及各种电子元器件需要轻薄的电阻器，电阻器元件厚度减薄后，不但元件的机械强度降低，而且通流容量减小，因此，如何寻求一种单位厚度的压敏电压值低、同时漏电流小的压敏功能材料，成了现在氧化锌制备行业急需要解决的问题。
发明内容
本发明提供了一种用于氧化锌压敏电阻器制备的材料，以解决现有的氧化锌压敏材料不能满足制造轻薄电阻器的需求的问题。
为了解决上述技术问题，本发明采用的技术方案概述如下：
一种用于氧化锌压敏电阻器制备的材料，由以下重量份的材料组成：
氧化锌93-96份；
氧化锡0.05-1.3份；
三氧化二铋1.5-1.8份；
氧化钇46-49；
氧化镱46-49；
二氧化硅9-12。
更进一步地，所述组分还包括硼酸0.05-0.08份。
更进一步地，所述氧化锌为纳米级氧化锌及微米级氧化锌中的任意一种或两种。
更进一步地，一种用于氧化锌压敏电阻器制备的材料，由以下重量份的材料组成：
氧化锌95份；
氧化锡1.2份；
三氧化二铋1.7份；
氧化钇47份；
氧化镱48份；
二氧化硅10份；
硼酸0.06份。
综上所述，由于采用了上述技术方案，本发明的有益效果是：
1.本发明的氧化锌压敏电阻材料中添加了三氧化二铋，能够促使烧结时形成陷阱和表面态而使氧化锌压敏电阻材料具有非线性，增加了压敏电阻材料的灵敏性；
2.本发明通过引入与锌离子半径相近的钇离子和镱离子(Y3+半径为0.088nm，Yb3+半径为0.09nm，Zn2+半径为0.06nm)，所得到的压敏电阻材料的非线性系数、较低的泄露电流、较强的抗大电流能力；
3.本发明制得的纳米氧化锌压敏电阻材料具有良好的电学性能稳定性；
4.本发明的氧化锌压敏电阻材料的制备方法成本较低、原料易得、且制备方法简单，具有良好的应用前景。
