Abstract

Indonesia has a quite large source of natural materials in the form of SiO2, AL2O3, CaO, MgO, K2O, Na2O which can be used as raw material for ceramic manufacture. Ceramic is material non-metals that have different characteristics and particular advantages with other materials which often cause failure on end product of ceramic, especially on ceramic tableware, with their black spot defect on its surface. Black spot failure that occurs on the surface of ceramic tableware can be seen from visual identification of defects in biscuits and white body. The failure analisys is using root cause Fault Tree Analisys (FTA), equipped with a variety of SEM and XRD material characterization testing. From the results of SEM and XRD material characterization test, the black spots derived from any element of Fe-based according to white body product SEM/EDS test, whereas for ceramic raw materials after XRD test not obtained the compounds Fe on the raw material, however obtained alluminum Iron Carbida compound in biscuit products. The conclusion of the black spots failure analisys on the surface of ceramic tableware ceramics is derived from the production process itself.
