Description

一种安全环保的非线性压敏电阻器及其应用
技术领域
本发明涉及电子元器件技术领域，具体涉及一种安全环保的非线性压敏电阻器及其应用。
背景技术
压敏电阻是其电阻随所加的电压变化而非线性变化的一种电阻原件，即当施加电压值超过某一阀值电压时，其电阻迅速变化的电阻器，是一种自身电阻对外加电压敏感，且可以反复使用而不会损坏的电子原件，也称为“突波吸收器”，它主要用来保护电子产品或电子原件免受开关或雷击头发所产生的影响。压敏电阻在不工作时，相对于被保护的电子元件而言，具有很高的阻抗(数兆欧姆)，而且不会改变设计电路特性，但当瞬间突波电压出现(超过压敏电阻的崩溃电压时)，压敏电阻的阻抗就会变低，只有几个欧姆，造成电路短路，从而保护电子产品或电子原件，压敏电阻具有良好的非线特性、通流量大、残压水平低、动作快和无续流等特点，可广泛应用于电子设备中，它是声像系统、计算机及通信设备中。
传统的氧化锌电阻器以氧化锌为主要材料，并包含多种微量的金属化合物，如三氧化二铋、三氧化二锑、二氧化锰、四氧化三钴、三氧化二铬等，主材料和多种金属化合物经混合、成型后在高温下烧结而形成的多晶多相的压敏电阻陶瓷片，但是这些压敏电阻器中含有较多的锑化合物，三价的锑化合物具有致癌作用，因此制备一种不含锑元素的安全环保的氧化锌压敏电阻器具有十分重要的意义。
发明内容
针对现有技术的不足，本发明提供了一种不含锑化合物的压敏电阻器，它具有安全无毒，对环境友好的优点，且残压比低，漏电流小，适合多种恶劣天气下的使用。
为实现以上目的，本发明通过以下技术方案予以实现：
一种安全环保的非线性压敏电阻器，由压敏电阻陶瓷片和导电电极组成，所述压敏电阻陶瓷片，由以下重量份的物质组成：氧化锌200-240份、二氧化锰1.2-1.8份、二氧化硅0.23-0.32份、二氧化钛0.25-0.3份、八硫化九钴0.5-1.2份、三硫化二镍0.5-1.2份、碳化硅0.03-0.15份、氮化锆0.2-0.8份、钛酸锆0.05-0.15份、钛酸铜钙1.5-2.5份。
优选的，所述压敏电阻陶瓷片，由以下重量份的物质组成：氧化锌200-240份、二氧化锰1.28-1.56份、二氧化硅0.25-0.28份、二氧化钛0.28-0.3份、八硫化九钴0.8-1.0份、三硫化二镍0.8-1.0份、碳化硅0.06-0.12份、氮化锆0.36-0.72份、钛酸锆0.08-0.12份、钛酸铜钙1.8-2.4份。
优选的，所述压敏电阻陶瓷片，由以下重量份的物质组成：氧化锌200份、二氧化锰1.48份、二氧化硅0.28份、二氧化钛0.3份、八硫化九钴0.95份、三硫化二镍0.95份、碳化硅0.07份、氮化锆0.55份、钛酸锆0.12份、钛酸铜钙2.1份。
优选的，所述氧化锌的粒径为10-50纳米。
优选的，所述八硫化九钴与三氧化二镍的质量比为1:1。
优选的，所述导电电极为金、银、铜、铝、镍、碳中的一种。
本发明的安全环保的非线性压敏电阻器的适用于功率二极管、硅堆、中小功率可控硅的过压保护。
本发明的有益效果：本发明对氧化锌进行掺杂，使掺杂原子进入氧化锌晶格占据并替代锌原子的位置，显著提高氧化锌的电导率和载流子浓度；掺杂还能细化氧化锌晶粒，降低尺寸，增加晶界表面密度，且掺杂后氧化锌压敏电阻的电阻率降低，从而降低了压敏电阻的残压比；本发明中二氧化锰能够改善压敏陶瓷的电阻非线性和稳定性，并且降低了氧化锌压敏陶瓷的电阻率；通过加入二氧化硅，既能改善压敏镀组陶瓷片结构的均匀性，还能提高压敏电阻器的势垒高度和非线性系数；加入八硫化九钴与三氧化二镍提高了氧化锌压敏陶瓷的晶面势垒高度，使压敏电压升高，非线性系数增加，漏电电流降低，且还能降低氧化锌晶粒的粒径，使材料更加致密；三氧化二钇提高了氧化锌晶粒的电导率，抑制氧化锌晶粒的生长，细化晶粒尺寸，提升了压敏电阻器的电压梯度。本发明通过对氧化锌材料进行掺杂，细化了氧化锌的晶粒，增加了压敏电阻陶瓷片的表面密度，改善了压敏电阻特性，提升了电阻器抗电流力冲击能力和非线性系数，使得压敏电阻器具有较高的电压梯度和有益的电性能，且对过电压响应速度达到纳秒级，过电压后恢复快，无续流，本发明的压敏电阻材料安全无毒，对人体和环境无害。
