Method for synthesizing calcium hexaluminate material by gel casting
The invention relates to a method for synthesizing a calcium hexaluminate material by gel casting. The method is characterized in that analytically pure Al2O3 powder and CaO powder are taken as main raw materials, acrylamide (AM) is taken as a monomer, N,N'-methylene bisacrylamide (MABM) is used as a cross-linking agent, triamine citrate is used as a dispersing agent, N,N,N',N'-tetramethylethylenediamine (TEMED) is used as a catalyst, ammonium persulfate (ASP) is used as an initiator, and premixed solution preparing, pulping, injection molding, demolding, drying and sintering are performed prepare a calcium hexaluminate material blank by adopting a gel injection molding method. The calcium hexaluminate material prepared by the method has the advantages of simple process flow, uniform material components and density, few defects, high green body strength, convenience in processing and the like, so that the comprehensive quality of a manufactured product is remarkably improved.
本发明涉及一种凝胶注模合成六铝酸钙材料的方法，以分析纯级Al2O3粉、CaO粉为主要原料，丙烯酰胺(AM)为单体，N‑N’‑亚甲基双丙烯酰胺(MABM)为交联剂，柠檬酸三胺为分散剂，N,N,N’,N’‑四甲基乙二胺(TEMED)为催化剂，过硫酸铵(ASP)为引发剂，采用凝胶注模的方法，经过配置预混液、制浆、注模、脱模、干燥、烧结制备六铝酸钙材料坯体，由本方法制备的六铝酸钙材料具有工艺流程简单，材料组分和密度均匀，缺陷少、生坯强度高，便于加工等优点，使所制造产品的综合品质显著提高。
