Alumina-Zirconia-Silica Ceramics Synthesis by Selective Laser Sintering/Melting

摘要

In this paper, the synthesis and investigation of the glass in the Al_2O_3- ZrO_2-SiO_2 system, to be used in dental field. The mechanism of powder–state becoming a solid state block during the laser sintering process was disclosed by scanning electron microscope (SEM) and energy dispersive X-ray (EDX) analysis on powders and sintered samples. The optimal parameters of laser and can be obtained by the study. The results allowed us to affirm that the characteristics of this glass, in comparison with the tooth hard substances and other commonly employed inorganic dental materials, recommend it for further utilization in the dental field.
