Composition for preparing NTC thermistor chip and NTC thermistor prepared from composition
The invention discloses a composition for preparing an NTC thermistor chip and an NTC thermistor prepared from the composition. The composition is prepared from the following raw materials in parts by weight: 865 to 895 parts of Mn3O4, 35 to 45 parts of Co3O4, 230 to 245 parts of NiO, 38 to 45 parts of SiO2, 180 to 220 parts of Fe2O3 and 40 to 60 parts of ZrO2. The composition with reasonable proportion is adopted, so that the prepared NTC thermistor is high in resistance value consistency and high in B value, the problem of resistance value drift and even failure after the thermistor is aged in a high-temperature environment for a long time is effectively prevented, the service life of the thermistor is prolonged, meanwhile, a certain proportion of zirconium oxide is added, the flexural strength of the resistor chip can be effectively increased, the problem of low flexural strength of the resistor chip is solved while a low-resistance product is obtained, and the electrical property of the NTC thermistor product is improved.
本发明公开了用于制备NTC热敏电阻芯片的组合物及其制成的NTC热敏电阻，由下列重量份原料组成：Mn3O4 865‑895份、Co3O4 35‑45份、NiO 230‑245份、SiO2 38‑45份、Fe2O3 180‑220份、ZrO2 40‑60份。本发明通过采用合理配比的组合物，可以使得制备的NTC热敏电阻的电阻值一致性好，B值较高，有效防止热敏电阻长期在高温环境下老化后出现阻值漂移甚至失效的问题，延长了热敏电阻的使用寿命，同时加入一定比例的氧化锆，可以有效增加其电阻芯片的抗折强度，在获取低阻产品的同时解决了其自身抗折强度低的问题，提高了NTC热敏电阻产品的电性能特性。
