title: [Studies on the synthesis of zeolite 4A in mirowave field by means of X-ray diffraction].
abstract: Good quality zeolite 4A with homogenous particle size, high whiteness and high calcium exchangeability was successfully synthesized in microwave field. The effects of the ratio of silica to aluminium, the ratio of water to sodium, the power of microwave, and the time of microwave heating on the synthesis of zeolite 4A were studied by means of X-ray diffraction. And the products were also characterized by IR, SEM and DSC. The optimal condition for the synthesis of zeolite 4A in microwave was found.
