A synthetic whitening composition is proposed as a whitening agent of porcelain tile body with a certain amount for the turning the body colour into whiteness. Active component used in the agent is zirconium silicate and this component is affected by the market speculation.This situation increases considerably the production costs. For these reasons an alternative whitening composition is required. The aim of the study is to prepare new whitening composition without zirconium silicate, with controlling crystalline phases in the porcelain stoneware tile, and to carry out characterization studies (such as XRD, SEM and EDX) and to correlate the whiteness value and the amount and type of crystalline phases in the porcelain tiles.
