Study on Synthesis of Linear NTC Sensitive Ceramic and Its Properties

Abstract:

The preparation method of CdO-SnO2-WO3 series (Cd-Sn-W for short), CdO-Sb2O3-WO3 series (Cd-Sb-W for short) and double-base three-phase (Cd2Sb2O7、CdSnO3、 CdWO4) structure linear NTC(Negative Temperature Coefficient)ceramics made of these two combined materials were studied. Six equations were independently designed, according to which NTC Sensitive Ceramic micro powders were prepared through chemical coprecipitation. The part that polyethylene glycol (PEG) and anhydrous ethanol played to prevent granules agglomeration when making nano-powders was deeply analyzed. As large formula weight polyethylene glycol (PEG) is not poisonous and does no harm to people’s health, it is worth popularizing widely
