Pengaruh Campuran Senyawa Boron Untuk Mengurangi Sifat Kegetasan

Abstract

It had been the manufacture of ceramics for construction materials with Clay, feldsfar, Kaolin and Quartz and Boron Compounds binder material. The based materials Variations composition are: 95,96,97,98,99, 100% (in mass%) had equal addition of boron compounds 1, 2, 3, 4, 5% (in mass%), with sintering temperature 1200°C detention for 4 hours. The Dimensions of test samples was made in form of beams. The test Parameter which was done meluded: Mass Lossed, Volume Lossed, Density, Porosity, Compressive Strength, Hardness, Strong Impact, and analysis of surface structure by Scanning Electron Microscope (SEM). The Result of physical testing was: Loss of Mass 17.18%, Loss of Volume 14.70%, Density 1.90 g/cm3, porosity is 0.55%, while as mechanic it had: Compressive Strength 5.40 Kg/Cm2, Hardness 86.90 kgf/ mm2, Strong Impact 0.89 J/cm2.
