Abstract

The present invention relates to a tin-antimony oxide conducting film and its production method. Said film contains (wt%) 80%-96% of tin dioxide and 4%-20% of antimony pentoxide, their grain size diameter is 10-20 nm, and thickness is 80-180 nm. Its production method uses aqueous solution of SnCL4 and SbCL3 ethyl alcohol solution as raw material and includes the following steps: using amkmonia water to make precipitation, using oxalic acid and ammonia water to make back-solvation, concentration, preparing sol-gel, ageing, high-temp. spraying on silex glass for tin-antimony oxide conducting film with high conductivity and light transmittance, and high heat exchange efficiency.

Description

Technical field: [0001] The invention relates to the technical field of a tin antimony oxide conductive film and a manufacturing method thereof. Background technique: [0002] At present, the commonly used electric heating technology is mainly conduction in the form of electric heating wire, tin antimony oxide conductive film, etc., and diffusion heating has been widely used in many fields for decades, but there have always been problems such as slow heating speed and low thermal efficiency. Difficult to solve, and long-term use, over-current between electrodes, easy to break, peroxidation of the heating element, easy to fall off, low dielectric strength, poor heat resistance, especially for the heating of water or other liquids requires a container with a certain volume, the heating process It is easy to scale, and it is difficult to separate water or other liquids from electricity. These shortcomings make it difficult to achieve electricity safety, thus limiting its use in...
