Abstract

Reduction of sintering temperature on the ceramic material can reduce operating costs and provide an effective time to companies manufacturing goods. Reduction of temperature sintering process can be carried out with the addition of fillers that is mixed with powdered clay from Claytan Company. For this study, sodium feldspar is used'as filler, and 5 temperatures have been selected as the parameters (850"C, 900°C, 950eC, 1000°C and 1050°C). Ceramic porcelain acquired from the Claytan's company is initially filtered through the process of milling and obtained a particle of size 125pm. The ceramic powder is then mixed with feldspar Claytan with 4%wt, 8%wt and 10%wt using a ball mill. The uniaxial compaction technique is performed to the powder to obtain a sample and then sintered at different temperature. TGA results show that porcelain ceramic of Claytan and feldspar has a degradation temperature of 510.5"C and 727°C respectively. Porosity and density results indicate a reduction in the percentage of porosity and an increase in density when the sintering temperature increases. In addition, the compression test and hardness test shows an increase in value when the temperature inreases. SEM micrograph shows with increasing of sintering temperature resulted in reduced porosity and high density in the sample. The addition of 4%wt feldspar in porcelain ceramics Claytan shows a better value compared to O%wt, 8%wt and 10%wt, where the percentage of lowest porosity is 21.2%,at a temperature of 1050 " C and the highest density value is 2.035 g/cm3 at a temperature of 1050°C. Besides that, additional of 4wt% sodium feldspar with a sintering temperature of 1050°C produce a ceramic material that can withstand a compressive force of 72.09 MPa
