英文摘要: Negative temperature coefficient (NTC) thermistors based on Ni 0.9Mn2.1-xMgxO4 (0&lex&le0.3) materials with different compositions were synthesized by a rheological phase reaction with ultrasound radiation (RPR-UR) method. It was found that the as-prepared powder crystallized well with spinel structure. It presented a microstructure of well-packed grains. The resistivity, B25/50 constant and activation energy with a wide range of values were obtained. And it can be adjusted to desired values for industrial applications by controlling the MgO content. All the results suggest that the RPR-UR method is a promising technique for the preparation of Ni0.9Mn2.1-xMg xO4 NTC ceramic materials.
