Using the methods of X-ray diffraction and scanning electron microscopy and the formation processes of the phase structure are investigated occurring in the preparation of rhombic calciummonoaluminate sol-gel process using as polymerization agents different oxoacids. The synthesis proceeds through the formation of calcium oxide, and the desired product formation occurs when using lactic acid. By using tartaric acid, malic acid and citric Fazoobrazovanie passes through to obtain calcium carbonate, the desired product is formed at a temperature 1000S. The shape and size of the particles formed using different oxoacids no significant effect
