Problems solved by technology

Ceramics have stable chemical properties, are not easy to react with other substances, and have stable heat generation and constant temperature. Therefore, they are often used in the field of precise temperature control. However, the preparation process of traditional ceramic heating elements is relatively complicated, and is subject to The limitations of conductive paste thick film materials severely limit the expansion of ceramic heating elements

Abstract

The invention relates to the technical field of ceramic materials, in particular to a porous conductive ceramic material for heating and a preparation method thereof. The porous conductive ceramic material comprises the following raw materials in parts by weight: 5-10 parts of ceramic powder, 1-5 parts of a binder, 0.5-2.5 parts of a pore forming agent, 20-30 parts of conductive bone meal, 5-10 parts of nanometer silicon powder, 10-20 parts of an organic carrier and 1-5 parts of an auxiliary conductive agent. According to the porous conductive ceramic material, the conductive mode of the porous ceramic material is used for replacing the conductive mode that the surface of a traditional ceramic material is coated with electronic paste, and a resistance heating wire or a printing heating circuit does not need to be additionally arranged; and when the porous conductive ceramic material prepared by the invention is used as a heating material of an electronic smoking set, a heating area is large, a heating surface is diversified and controllable, atomization is sufficient, the complex conductive mode of a traditional electronic smoking set heating material is changed, and the complexity of the preparation process of the heating material is reduced.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to a porous conductive ceramic material for heating and a preparation method thereof. Background technique [0002] The heating elements used on the atomizer mainly include metal heating elements and ceramic heating elements. Metal heating elements are divided into metal heating elements or heating wires. The materials include iron-chromium-aluminum, stainless steel, nickel-chromium alloy, pure nickel, pure titanium, etc. It is the simplest and most common heat source. It has the advantages of fast heat generation, long life, and low price, so it is widely used. However, the defect of the metal heating element is that its chemical properties are active, and it cannot be used in corrosive environments such as acid or alkali; Odor, affect the user's taste. [0003] The ceramic heating element is based on high-purity ceramics, and the surface is printed with resistance past...
