High curie point positive temperature coefficient resistance material Ba2BiTiV3O13 and preparation method thereof
The invention discloses a lead-free high curie point positive temperature coefficient resistance material and a preparation method thereof. The chemical composition of the high curie point positive temperature coefficient resistance material is Ba2BiTiV3O13. The method includes: weighing and blending BaCO3, Bi2O3, TiO2 and V2O5 original powder with purity of over 99.9% (weight percentage) according to the composition of Ba2BiTiV3O13, carrying out ball-milling, calcinations, secondary ball milling, granulation, molding, rubber discharge, high temperature sintering, loading on an Ag electrode and the like to obtain the lead-free positive temperature coefficient resistance material with a curie point up to 370DEG C. The resistance material prepared by the method provided by the invention dose not contain lead, avoids the harm of lead to human health and the pollution to the environment. The high curie point positive temperature coefficient resistance material provided by the invention has the characteristics of low sintering temperature and low raw material cost, reaches the practical level, and is suitable for industrial large-scale production.
