摘　　要：试验采用高纯超细氧化锆粉体为原料,通过凝胶注模成形工艺,获得氧化锆陶瓷刀具的坯体。参照已有经验,通过研究氧化锆陶瓷凝胶注模成形工艺流程及工艺参数与所得样品的关系,进行探索性试验。通过对比试验结果,获得最佳工艺参数,确定了氧化锆凝胶注模成形的最佳配方。按照试验提供的原料配方,严格控制干燥过程和烧成制度,可以得到结构致密、性能稳定、强度较高的陶瓷刀具,为凝胶注模成形方法的工业化推广提供了可靠的参考依据。The experiment has used a high--purity uhrafine zirconium oxide powder as raw material, through the gel mould molding process,get zirconia ceramics tool billet body. Experimental reference existing experienee, through research zirconia ceramics gel note lhe forming process trod the relationship between the process parameters and samples exploratory experiment. Through contrast experiment results,get the best technical parameters,determine the zirconia gel mould molding the best formula. According to the raw materials formula the experiment provided, strictly control the drying process, burning system, can get compact structure, stable perform;trice, high intensily of ceramic cutting tools. The experiment lay a solid foundation for the forming methods of gel moulding technology ,and it provide reliable reference for the industrialization promotion.
