Barium titanyl oxalates (BTO) has been homogeneously prepared by thermal decomposition of dimethyl oxalate (DMO) in hydrochloric solution containing <TEX>$Ba^{2+}$</TEX> and <TEX>$Ti^{4+}$</TEX>. Particles of BTO settled on the bottom of the beaker were collected at the aging time of 120 min using hydroxy propyl cellulose (HPC) as a dispersant. The reaction temperature, the concentration ratio of <TEX>$[DMO]_0/([Ba^{2+}]_0+[Ti^{4+}]_0)$</TEX> and the existence of HPC were found to influence on morphologies of BTO, chemical yields and characteristics of barium titanates formed from their precursors.
