Electronic paste composition, and preparation method and use of the same

Abstract

The present disclosure provides an electronic paste composition and a preparation method thereof. The electronic paste composition comprises tungsten, manganese, an additive, and an organic vehicle, wherein the additive is selected from at least one of ruthenium, tellurium, germanium, and vanadium. The preparation method comprises: mixing tungsten powder and manganese powder with the additive, and then bringing a mixture as acquired into contact with the organic vehicle. In addition, the present disclosure further provides a use of the electronic paste composition in preparing a ceramal heat generation body having a low temperature coefficient of resistance. The electronic paste composition according to the present disclosure and the electronic paste prepared by the method according to the present disclosure have a consistent and low temperature coefficient of resistance. Thus, when the electronic paste composition is applied into the ceramal heat generation body, it may ensure that the resistance of the product after fired changes little by temperature in the process of use, thereby allowing a simple circuit and a high overall heat generation reliability.
