The aim of the present study is to prepare bone china porcelain from Iraqi raw material (IRM).
Three set compositions were tested in this work: Set No.1 Iraqi Raw Materials (Calcined Akashat Phophorite, Duekhla Kaolintic clay, and Dibbdiba Feldspathic sand), Set No.2 standard raw materials (Bone Ash, Kaolin A, and Nepheline Seynite), Set No.3 (Iraqi Raw material base with Bone Ash and/or Tricalcium Phosphate).
Raw materials powders were tested by XRD, thermal analysis (DTA and TGA), and FT-IR, before and after heat treatment.
Chemical composition, mineral phases and microstructure in bone-china bodies were determined by XRD, scanning electron microscopy (SEM), and EDX (Energy Dispersive X-Ray Spectroscopy).
The influence of phosphate nature (type), phosphate, kaolin, feldspathic sand percentage, and temperature were discussed on the final mineral association of the fired bone china.
It clearly shows that fired bone-china bodies consist of whitlockite and/or flouroapatite, anorthite, and quartz unevenly dispersed in a complex glassy matrix.
The estimated results of bulk density (BD) (bulk and solid), apparent porosity, water absorption and shrinkage are acceptable compared with standards.
The highest shrinkage% using standard materials with tricalcium phosphate (STD with TCP) (16.07%) and the lowest shrinkage% in Iraqi raw materials (IRM) bone-china bodies (12-238%) is explained mainly in terms of the presence of quartz.
Iraqi raw materials (IRM) bone-china bodies with (15-20%) bone ash gave acceptable whiteness.
The whiteness, yellow index determined indicates that the Iraqi raw materials (IRM) bone-china bodies off color is affected by the presence of impurities (Fe, Ti, Mn, and Co)
