Abstract:

This study includes the preparation of porcelain samples from different compositions. It also comprises the possibility of adding different melting materials, including (fluorescent candles glass waste (FLGW), borax) to porcelain material samples in different proportions as a substitute for potassium feldspar and studying its effect on the sintering behavior, microstructure, physical properties, mechanical properties and thermal conductivity of porcelain samples. The results manifested that increasing the percentage of potassium feldspar in porcelain samples led to improve physical properties, mechanical properties, and decreased thermal conductivity. The addition of flux materials caused a decrease in the sintering temperature to (1000ºC) when adding 5 wt%. of waste fluorescent candle glass and to (950ºC) when adding 5 wt.% of borax, compared to samples without addition, which required a sintering temperature of (1225ºC) to obtain the appropriate physical and mechanical properties. When increasing the proportion of flux in the porcelain samples to 10 wt%, it led to the formation of closed pores in the samples, and this resulted in to a reduction in the physical and mechanical properties of the porcelain samples.
