摘　　要：ＺｎＬｉＦｅＯ３（ＺＬＦ）高温ＮＴＣ热敏厚膜材料，是以尖晶石结构的ＺｎＬｉＦｅＯ３导电陶瓷作厚膜浆料的导电相，以Ａｌ２Ｏ３瓷为基体，用厚膜工艺制成的。实验表明，在氮气中烧结的ＺＬＦ厚膜材料，室温方阻１０３Ω／□级，Ｂ值约１０００Ｋ。在高温５００～７００℃范围内，方阻降为１０２Ω／□级，Ｂ值仍小于１０００Ｋ。是一种很有前途的高温热敏材料。The thick film ink is made from ZnLiFeO 3 of spinel as conduct phase When coated on Al 2O 3 substrates and fired in nitrogen atmosphere, at room temperature, the sheet resistance is 10 3Ω/□, B value is around 1 000 K ; at the temperature range of 500 ℃ to 700 ℃ the sheet resistance reduced to 10 2 Ω/□, but the B value is still around 1 000 K (5 refs )
