Studi Analisis Simulasi Tentang Korelasi Suhu Sintering dan Waktu Pembakaran Terhadap Sifat Mekanis Keramik PSZ dengan Aditif MgO

Abstract

Partially Stabilized Zirconia (PSZ) is a toughness ceramic so that can be used by toll cutting and bio ceramic. Have been done by ceramic making of PSZ ,Yith additive 12% mole MgO. Ceramic which have been printed by sintering at temperature 1 ]00°C until 1500°C ,with interval increase of temperature 100° and each arrested by during 3 hours. Analyzed by characteristic is simulation cover sintering temperature correlation to nature of mechanical tor example: densitas, porosity, hardness, fracture toughness, banding strength and coefficient thennal expansion. Simulation analysis done by using language programming of Mathematica Windows Version for 5.0. Pursuant to result of simulation analysis obtained is: ceramic of Mg-PSZ with additive 12% mole MgO optimum condition reached by at sintering temperature 1545°C yielding densitas value 5,71058g/crn porosity 8,19829% and banding strength 609,327xl06Pa. At sintering temperature around 980° -125 5°C yielding hardness value (Vickers hardness) (4.05749-1 L0012)xl09Pa and value fracture toughess around (l:l7325-l,7307)~106Pa--/m. Coefficient thermal expansion ,which is best. to be obtained at sintering temperature around 1554°C-1985°C with value around (12,0186-15,0056)x10-6-6C°-1
