Description
technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a technology for preparing nanometer ceramic particle materials by using industrial propane as a fuel flame vapor deposition method. Background technique [0002] Due to the unique physical and chemical properties of nanomaterials, the processing and synthesis technology of nanomaterials, especially nanoparticle materials, has been listed as a priority field of new materials by various countries. Traditional particle material processing and synthesis methods used in the processing and synthesis of nanoparticle materials have disadvantages such as complex process. Although the existing flame vapor deposition method for preparing nanoparticle materials has a simple process, due to the use of carbon monoxide or hydrogen as fuel, the prepared nanoparticle materials are expensive and difficult to market. High production cost is the bottleneck problem restricting the...
