Studi Tentang Korelasi Temperatur Sintering Terhadap Sifat Fisis pada Waktu Pembakaran Tetap pada Keramik Porselen Alumina Secara Simulasi

Abstract

Research about influent of Alumina composition has been done for making of ceramic of alumina porcelain. The applied raw material were Feldspar, Clay and Quartz, with addition alumina was varied from 0%, 5%, 10%, 15%, 20% of total weight. The samples test sintering with variation temperature from 1100°C until 1500°C and hold for 2 hours. The samples test after sintering were characterized such as : density, porosity, hardness, bending strength · and coefficient thermal expansion and the analysis used simulation of Computer programming language with Mathematic for Windows Version 5.0. According to the result measurement, the percentage of alumina can give significant influent for density, porosity, hardness, bending strength, and coefficient thermal expansion for ceramic porcelain.
