[KeywoHIs] gold-platinum (Au-Pt) alloy; preciousmetalceramicalloy; metallcga ~ phy; microsegregation observed in previous experiments BioHeradorN gold ceramic alloy was cast two phases: the matrix phase is spherical, uniform thinning,[link widoczny dla zalogowanych], light brown yellow ; the second phase is a small irregular white particles scattered in the matrix grain boundary area uJ. Overall, the cast alloy showed homogeneous equiaxed fine particles, proved that the class through the casting alloy suitable for forming, this should be class based alloy with excellent performance. So, what these two phase differences in the composition, the existence of segregation (Segre-gationphenomenon), we used cast their spectrum analyzer (EDX) carried out a preliminary analysis. Materials and Methods 1. Eco-materials and equipment BioHeradorN gold ceramic alloy; Her-avestSpee (1 Fast warm-type high-temperature-embedded material; CL-G97 Heraeus vacuum pressure casting machine (Heraeus Kulzer Dental Ltd.); S a 27o0SEM spectrometer with a 4 EDAXDX (HITACH1 Japan). 2. Methods 2.1 Preparation of conventional wax-type casting diameter 2mnlX40i/lnlX3; required by manufacturers and embedded in roasting; graphite crucible, CL-G97-type casting machine casting, casting After cooling to room temperature casting ring; sandblasting, steam cleaning. 2.2 Preparation of test specimens were intercepted in the middle of each cast specimen thickness 5i/lnl, initial file level,[link widoczny dla zalogowanych], with self-curing resin inlay; followed by 600 #, 800 #, 1000 #, 1200 #,[link widoczny dla zalogowanych], 1400 # metallographic abrasive paper; using canvas, velvet polishing; alcohol to clean the residue, distilled water rinse, drying; finally etched with aqua regia 90S. 2.3 spectrum analyzer to corrosion Specimen after a 2700 home with EDAXDX HITACHIS spectrum analyzer for a 4 component analysis.
