Na_2O对定向空心叶片陶瓷型芯质量的影响

Effect of Na_2O on This Ceramic Core Quality of the Directional and Hollow Blade’s

讨论定向空心叶片用XD 1陶瓷型芯质量与焙烧用的Al2 O3 填料化学成分的关系 ,指出Na2

A relationship between quality of Type XD-1 ceramic core and composition of alumina filler for core sintering is described, and the reason that an excess of Na_2O content would lead to ceramic core quality degradation is also put forward.
