KARAKTERISTIK BAHAN BAKU KAOLIN UNTUK BAHAN PEMBUATAN BADAN ISOLATOR LISTRIK KERAMIK PORSELEN FUSE CUT OUT (FCO)

Abstract

Kaolin is one of a very important raw material for fine porcelain ceramic production and the kaolin resources can be found in many places in Indonesia. Kaolin characteristic tests which include (chemical, physical, furnace, mineralogy, grain size) showed that the sample 1 and 2 do not meet the standard of porcelainceramic raw material. Fe2O3 concentrations of sample 1 and TiO2 concentrations of sample 2 were below SNI standard. In order to meet the SNI standard for isolator, post processing are required. These can further be important for the development of medium to high voltage isolator industries in Indonesia.
