摘      要：Zeolite A has been successfully synthesized from geothermal waste with natrium aluminate and natrium silicate using conventional(C-H)and microwave heating(M-H)for the hydrothermal *** products obtained for different aging times have been characterized using X-Ray Diffraction(XRD),Fourier transformation infrared spectroscopy(FTIR),and scanning electron microscopy(SEM).It is shown that with the M-H process,zeolite can be formed at relatively low temperature(100°C)in a relatively short time(40 min).The crystallization of zeolite A has been found to be generally promoted by an increase of aging and synthesis time;however,it has also been observed that relative long aging times can transform it into *** A produced through the M-H process generally displays a smaller and more homogeneous crystal size with respect to that obtained with the C-H method.
