Abstract The paper presents the application of 2-carboxyethyl acrylate as a new monomer in gelcasting of alumina. The research showed that the use of 2-carboxyethyl has a positive influence on the properties of green bodies, limiting the negative effect of oxygen inhibition. Oxygen inhibition which hampers polymerization reaction is a well known negative phenomenon in gelcasting but still not fully overcome for samples formed in air atmosphere. As a reference monomer 2-hydroxyethyl acrylate was used in the research. Rheological behavior of alumina suspensions containing both monomers has been studied, as well as the properties of green and sintered bodies obtained by gelcasting have been measured. The differences in the rheological properties and thus ceramic-monomer interactions in the slurries has been analyzed. The high values of densities and mechanical strength, accompanied with the pictures of microstructures of sintered ceramic parts have been presented, as a result of a successfully completed gelcasting process of alumina powder.

丙烯酸 2-羧乙酯作为一种新型单体，可防止氧化铝凝胶注模过程中氧抑制的负面影响

摘要 本文介绍了丙烯酸2-羧乙酯作为一种新型单体在氧化铝凝胶注模中的应用。研究表明，使用 2-羧乙基对生坯的性能有积极影响，限制了氧气抑制的负面影响。阻碍聚合反应的氧抑制是凝胶注模中众所周知的负面现象，但对于在空气气氛中形成的样品仍未完全克服。研究中使用丙烯酸 2-羟乙酯作为参比单体。研究了含有这两种单体的氧化铝悬浮液的流变行为，并测量了通过凝胶浇铸获得的生坯和烧结体的性能。已经分析了流变特性的差异以及浆料中陶瓷-单体相互作用的差异。
