White Porcelain Material Based On Diopside

The intention of the present study was to develop an alternative composition for making porcelain material using diopside as the main raw material. Particle size distribution, X-ray diffraction, X-ray fluorescence spectrometer, and field emission scanning electron microscope were carried out to characterize the body. Alfaquartz, diopside, anorthite, and clinoenstatite were major phases of fired sample. The flexural strength, 131.54 MPa, was two times higher than that of conventional porcelains. During firing, iron ions were diffused into diopside crystal lattice giving the porcelain body a favorable whiteness. It is applicable in preparation of porcelain material using diopside as the main raw material.
