Brief description of embodiments of resistors, in particular of thermistors, a coefficient of temperature greatly negative

摘要

P process for the preparation of thermistors, ctn discoid. It consists in mixing a material for resistors formed of a mixture of mgo and tio2, containing at least 30% of tio2 and having been crushed into a powder of 2 to 500 mu m with another material formed of a mixture of mgo and tio2, in a ratio ranging from 5: 95 to 95: 5, the cold resistance of the second material is greater than that of the first. Application to the production of the thermistors at highly negative temperature coefficient, but at a high specific resistance. / p
