Phi沸石的合成采用两种方法。X射线粉末衍射和扫描电子显微镜的结果表明，材料是菱沸石和菱钾沸石的物理混合物，一个样品有少量的钙钛矿。从这些样品的X射线粉末衍射数据，和那些以前报道的，索引和它们的晶胞参数比较以及从菱沸石和菱钾沸石的物理混合物中获得的那些。这些样品显示出指示物理混合物的多种颗粒形态。Phi沸石是菱沸石和菱钾沸石的物理混合物，我们建议停止使用Phi沸石的名称。
Zeolite Phi is synthesized by two methods reported previously. Results from X-ray powder diffraction and scanning electron microscopy suggest that the materials are physical mixtures of chabazite and offretite; one sample has a small amount of phillipsite. The X-ray powder diffraction data from these samples, and those reported previously, are indexed and their unit-cell parameters compare well to those obtained from a physical mixture of chabazite and offretite. These samples show multiple particle morphologies that are indicative of physical mixtures. Zeolite Phi is concluded to be a physical mixture of chabazite and offretite and we suggest that the use of the name zeolite Phi be discontinued.
