Abstract

During this time in the process of making and mixing which is done for the manufacture of ceramics (green body) is very easy to break and change shape before heating. However, when mixed with polyethylenglycol (PEG) it is not easily broken and deformed and functions as a binder. Furthermore, an analysis of the variat ion of the composition of the binder on the microstructure and the effect of the suppression of silica sand pellets to determine the effect of the composition on the microstructure and the results of the suppression. Then the heat is treated in a furnace w ith a different composition. In sample 1 the SEM - EDX test obtained irregular chunks with sizes varying between 504μm - 2,750 μm and the compressive strength results of 503.89 Pa, sample 2 of the SEM - EDX test obtained results of irregular chunks and flat gr anules irregular with sizes varying between 321 μm - 1,100 μm and the compressive strength results of 462.55 Pa, sample 3 SEM - EDX test obtained irregular chunks with sizes varying between 458 μm - 1,283 μm and the results of compressive strength 413 Pa. We recommend that in the selection of compositions used for the manufacture of ceramics, the use of silica sand below 85% and PEG above 15% because the compressive strength produced is quite high at 503.89 Pa.
