Copper is the most important raw material for cold-water plumbing systems in private and public buildings. One disadvantage of copper pipes is that small amounts of copper dissolve into the drinking water. Protective layers of cuprite (anodic coating

X-ray diffraction patterns of gypsum exhibit different reflection intensities, depending on the conditions under which the gypsum was manufactured. Pole figures and area detector images have shown that these differences in intensity result in large p

As shown in Part I, in the case of organic substances with two crystallographically independent molecules, crystallographic and affine symmetries determine crystal growth. The Fourier transform method was used to calculate the theoretical growth form

Investigations of the growth of sucrose single crystals (P2 1 ) were conducted in pure solutions with 10% supersaturation at 22 and 50°C and in the presence of fructose and glucose. In the first 2–3 h, dissolution was observed at the positive end

Three different types of growth forms of sucrose (P21) were found by calculating with the Fourier transform method of crystal morphology. The observed central distances of the (100) and (001) faces are smaller than those calculated. It will be shown

In highly supersaturated solutions, potassium dichromate crystals exhibit a growth anomaly on (001): this face is rough and covered by many potassium dichromate platelets that are only a few μm thick, even though the structure is centrosymmetric. Th

The structure of potassium dichromate (P1, Z = 4) consists of two layers parallel to (001), between which no crystallographic symmetry relation exists. These layers are nearly coincident with each other when rotated through 90° about c * . One quest
