Aluminum oxide hollow sphere heat insulation product containing chromium oxide
The invention belongs to the technical field of refractory materials, and in particular relates to an aluminum oxide hollow sphere heat insulation product containing chromium oxide. A preparation method of the aluminum oxide hollow sphere heat insulation product comprises the following steps: by taking aluminum oxide hollow spheres as aggregates, adding alpha-Al2O3 powder, chromium oxide fine powder and chromium oxide powder as substrates, adding a binding agent, performing material mixing, molding and drying, and performing high-temperature firing to prepare the aluminum oxide hollow sphere heat insulation product. According to the aluminum oxide hollow sphere heat insulation product disclosed by the invention, the alpha-Al2O3 powder and chromium oxide raw materials are subjected to reaction, and a formed aluminum-chromium solid solution is taken as a heat insulation product substrate so as to ensure that the product has the characteristics of good wear resistance, excellent erosion resistance, excellent thermal shock resistance, high strength and the like.
