| Abstract | The Calcium silicate porous glass-ceramic material was prepared by using cheaper calcium carbonate from eggshell in this study. The key morphological characteristics of the porous glass-ceramic product were assessed and the capability of this material in body fluid was investigated. The porous glass-ceramic orbital implants derived from different eggshell contents (30 50 mol%) in replacement of calcium carbonate in calcium silicate glass systems were fabricated. The microstructure, phase composition, and porosity of glass-ceramic orbital implants both after fabrication at 870บC and 1000บC for 2 h and 5 h, and after immersion test in Simulate Body Fluid (SBF) solution for 2 weeks and 1 month were comparatively studied. The maximum contents of eggshell in making the calcium silicate glass is 40 mol%, in which a pure amorphous structure was formed for the fabrication of a glass-ceramic orbital implant. The biocompatible wollastonite phase was obtained after heat treatment at 1000บC for 2 h. The glass-ceramic orbital implants from eggshells have a uniform distribution of an open-macropore with high porosity in the range of 35-45% for eye tissue ingrowth. Also, good chemical stability in SBF for a 2-month test was obtained in this alternative low-cost eggshell derived porous glass-ceramic for ocular prosthesis applications. |
