Karakterisasi dan Studi Sebaran Kobalt Sistem Badan Keramik Lempung Bojonegoro – Feldspar – Kuarsa
ABSTRACT: The quality
improvement of Bojonegoro Clay and the cobalt distribution on the surface of
ceramic body system have been studied. The ceramic body system consists of
Bojonegoro Clay, feldspar and quartz is optimized using a triaxial blend
method. About 6 compositions among 15 compositions of synthesized ceramic
bodies can be casted in plastic condition with plastic limit between 22 and
30%. It has been obtained that the optimum composition of the ceramic body is
57% clay, 14.5% feldspar, 28.5% quartz with the total shrinkage is 7 % and the
modulus of rupture is 18.23 N/mm2. Cobalt is distributed homogenously on the
optimum ceramic surface with 0.3 mm depth at optimum glaze firing temperature
(1050oC).
