Abstract
The invention provides a making method of heat and electric conducting silica gel, sequentially comprising the following steps of material selection, purification, hydrolysis, stirring and boiling, cooling precipitation, centrifuge dripping, washing during boiling, and drying and firing. The silica gel with heat and electric conduction can be obtained through the making method, and the method hasthe advantages of simple process and low making cost of the heat and electric conducting silica gel. The invention also provides a heat generating device adopting the silica obtained by adopting the making method as a heat generating body, comprising a power supply, an electric conducting wire, and at least two unconnected and non-viscous heat and electric conducting silica gel sheets obtained bythe making method and a switch connected with the power supply, wherein the heat and electric conducting silica gel sheets are electrically connected by the electric conducting wire. The heat generating device has the advantages of capability of washing, good constant-temperature effect, no pollution and the like due to the property advantage of the heat generating body.
