This part of the study involves the investigation of the interactions between an ABS type commercial leadless glaze and a biscuit fired bone china body during glost firing at different temperatures using XRD and SEM techniques. The aim was to obtain detailed and systematic information about the morphological and chemical characteristics of the resultant phases formed at the interfaces. Separate examination of the interactions between the glaze and the experimental crystalline phases of the body prepared earlier, namely anorthite and beta-TCP. were also carried out in an effort to show their susceptibility to react with the glaze independently. As a result, the presence of a range of interaction layers with distinctly different morphological and chemical characteristics was successfully demonstrated. It was proposed that beta-TCP was the major contributor to the overall interactions by reacting with CaO from the glaze in the presence of water vapour and forming hydroxyapatite crystals at the glaze-body interfaces. Although the exact origin for the development of water vapour in the molten glaze could not determined, several potential sources were suggested. (C) 2002 Elsevier Science Ltd. All rights reserved.
