| dc.description.abstract | The aim of this study is to optimize clay-bonded graphite crucible from the mixture of clay and graphite and selected additives (MgO and SiC) using D-optimal under the Mixture Methodology of the Design-Expert version 6.08. The samples were dried forced under the normal atmospheric condition for two weeks and were oven dried at 100oC and later fired in a muffle furnace at 11000C. The samples were subjected to the following mechanical test bulk density, linear firing shrinkage, and apparent porosity. The results obtained shows that experimental Run 7 gave the least value of bulk density (1.80) with Clay (80 %), Graphite (10 %) and MgO and SiC (10 %) respectively but Run 9 gave the lowest apparent porosity with Clay (70 %), graphite (10 %) [MgO and SiC (10 %)]. Further investigation conducted indicated that Run 13 with percentage composition of 80 % clay, 10 % graphite, 5 % MgO and 5 % SiC gave the highest value of the bulk density of 2.91 and the least value of linear shrinkage of 2.15 and the apparent porosity value of 28.20. These values fall within the experimental range given by literature. Though by natural intuition and from the literature survey, run 14 would have been selected but based on values obtained, run 13 was confirmed and concluded upon to have a better composition as a result of the computer analysis using design expert considering the values obtained from the selected mechanical test | |
