在此，Al掺杂的Mn1.95Co0.21Ni0.84O4（MCN）-微珠结构成功地制备使用原位喷墨打印技术。讨论了Al 2 O3掺杂对MCN陶瓷微球电性能的影响。NTC陶瓷热敏电阻的R-25、B-25/50和E-a值分别为14.14 × 10（3）-63.21 × 10（3）Ω、3635-3773 K和0.3133-0.3252 eV。值得注意的是，发现（Mn-Co-Ni-Al-O）MCNA陶瓷的老化系数（Δ R/R）为
Herein, Al-doped Mn1.95Co0.21Ni0.84O4 (MCN)-microbead structures were successfully prepared using in situ ink-jet printing technology. The effects of the Al2O3 doping on the electrical properties of the MCN ceramic microbeads were discussed. The R-25, B-25/50, and E-a values of NTC ceramics thermistors were found to range from 14.14 x 10(3)-63.21 x 10(3) omega, 3635-3773 K, and 0.3133-0.3252 eV, respectively. Notably, the ageing coefficient (Delta R/R) of the (Mn-Co-Ni-Al-O) MCNA ceramics was found to be
