摘　　要：用龙岩高岭土合成４Ａ沸石，成胶过程采用磁力搅拌代替机械搅拌，高岭土的利用率可提高２０％～３０％；产品质量以钙交换能力计，平均达到２９８ｍｇＣａＣＯ３／ｇ干沸石；粒径１μｍ．并就作用机制进行了探讨．In the formation process of colloid for the synthesis of 4A zeolites from Longyan kaolin, the utilization rate of kaolin can be raised by 20%～30% by use of magnetic stirring instead of mechanical stirring. The calcium ion exchange capacity, on the average, reached 298 mg CaCO 3/g dry zeolites. The particles have about 1 μm in size. The mechanism of reaction is also discussed.
