| Abstract: | The formation and solubility of rare earth element N-containing melilite solid solution were studied by preparation of specimens with the general formula R2Si3--xAlxO3 xN4-x (R=Nd,Sm,Gd,Dy and Y) byhot pressing and pressureless sintering in the temperature interval 1600-1700"C. The results indicate thatmelilite and its solid solution are more easyly formed in light rare earth systems, but the solubility limits decrease with decreasing the i..i.'.adii of rare earth elements. For E=Nd, up to one St can be replaced by Al. |
