摘要
利用国产化的原材料和常规的ＰＴＣ陶瓷生产工艺，制备了适宜于摩托车用的ＰＴＣ陶瓷发热元件，该元件的居里温度Ｔｃ≈１１０℃、室温电阻率ρ２５℃≈２８Ω·ｃｍ、电阻温度系数α≈１６．０／％℃－１、电阻突跳度Ｒｍａｘ／Ｒｍｉｎ＞１０５、表面温度Ｔｓｕｆ＝１３５±５℃；且有良好的耐电流和稳定性。
The PTCR ceramics heaters for the motorcycle has been made by using home made raw materials and conventional preparation processes. It has Curie temperature, T c≈110℃, room temperature resistivity, ρ 25 =28Ω·cm, temperature coefficient of resistivity α ≈16/%℃ -1 ,resistivity jump R max / R min >10 5,surface temperature, T suf =135±5℃, excellent withstanding current and stability.
