KERAMIK PORSELEN BERBASIS FELDSPAR SEBAGAI BAHAN ISOLATOR LISTRIK
Abstract: Electric solid
insulator based on ceramics porcelain had been made by using local raw
materials: 68% feldspar, 10% kaolinite and 22% quartz, and also added 0%, 5%,
10%, 15%, 20%, 25% cullet (From total mass). The forming process of the
porcelain was conducted by milling the raw materials using ball mill and
screened using 200 mesh screening. The samples were formed by using the
dry-press method with the pressure of 50MPa, then the samples is sintered at
temperature of 1000oC, 1050oC, 1100oC, 1150oC for 2 hours. The properties of
the samples had been analyzed for their
shrinkage, density, bending strength and resistivity. The result of the
experiment showed that the optimum value was reached by ceramic which was added
by 15% cullet and sintered at temperature of 1100oC. This ceramic had shrinkage
of 9,70%, density of 2,44 g/cm3, bending strength of 86,73 MPa and the
resistivity at 25oC is 2,32x108 Ωcm
