Evaluation of CoAl2O4 as ceramic pigments - ScienceDirect
Most of the ceramic dyeing materials possess the spinel structure. The main aspect of spinels is the presence of two metallic cations, A 2+ and B 3+, in tetrahedral and octahedral positions, respectively. The manner in which such sites are occupied depend on the calcining temperature [1], [2]. CoAl 2 O 4 is a double oxide with a normal spinel ...
The Steam Revolution – Creatures of Thought
Even in Britain, water-power continued to overshadow steam-power in both number of mills and operating horsepower well into the nineteenth century. In other countries with more abundant water sources, less industrial know-how, and more expensive coal, water power continued to dominate steam even into the second half of that century.
dye - Synthetic dyes | Britannica
The synthetic dye industry arose directly from studies of coal tar.By 1850 coal tar was an industrial nuisance because only a fraction was utilized as wood preservative, road binder, and a source of the solvent naphtha.Fortunately, it attracted the attention of chemists as a source of new organic compounds, isolable by distillation.A leading researcher in this area, German chemist …
