摘要：

Different crystalline structures of linear trans-quinacridone were prepared and analysed by combination of X-ray diffraction, specific surface areas, optical and scanning electron microscopy, infrared spectroscopy, spectrophotometric analysis and differential thermal analysis. The lattice parameters of each crystalline phase were determined by X-ray diffraction. A new crystalline phase of this pigment was obtained and named the zeta-phase. Isothermal crystallization studies indicated that the crystallographic texture induced by pressure has a strong influence on the crystallization behaviour of this dyestuff.
