The dry grinding causes aggregation of fine particles even in early stage of grinding, while the wet grinding reduces the particle size of the product. The sintered bodies from the products ground in wet using water possess large cracks, while they are fairly free from the defects when the mixture was ground in alcohol. Wet grinding in methanol with high (f1 IV) value is more advantageous for producting dry fine particles, resulting in the improvement in characteristics of NTC thermistor with high density.}, pages = {13--19}, title = {NTCサーミスタ合成に及ぼす粉砕の影響}, volume = {14}, year = {2001} }
