A Copper hydroxide-vermiculite complex (CHVC), Cu1.61(OH)2.38(Si2.95Al1.05) (Mg2.75Fe0.22Ti0.02)O10(OH) 2· nH2O, having a particle size in the range from 1 to 3 mm was prepared from a Zimbabwe vermiculite by hydrothermally treating at 250°C for 40h in copper nitrate solution. X-ray diffraction patterns of the products were characterized by d001 reflection of 1.4 nm and their subsequent interger reflections. One-dimensional Fourier electron density analysis revealed that the interlayer structure of CHVC is similar to that of a natural chlorite. The thermal behavior of CHVC was characterized by high temperature X-ray diffractometry and TG-DTA technique. Copper hydroxide in the interlayer was dehydroxyrated in the temperature range from ca. 300 to 700°C. By heating at higher temperature, copper oxide deposited on the sur-face of the silicate layer.
