Stoneware Ceramic Synthesis with Iron Sand as a Filler Material

Abstract

In an effort to explore the use of natural resources, stoneware ceramics have been made using iron sand as a filler to replace quartz Kalimantan. The results showed that iron sand can be well used in making stoneware ceramics. This is shown by the measurement of water absorption which is less than 5% and has compressive strength slightly smaller compared to stoneware ceramics made with quartz as a filler.

Cocoa Cortex Ashes as Fluxing Additive for Vitrified Ceramic Making from Alluvial Clay

“…Vitrified ceramics are manufactured either from a clay alone containing enough amounts of fluxing oxides or from a mixture of poorly fluxing clay and additive fluxes. The firing temperature is usually between 1120˚C and 1300˚C [2] [3] [4]. Low sintering temperatures lead to insufficient maturation and less compact products with important amount of pores.…”
