When a metal is oxidised in carbon dioxide, the growth of oxide film may be accompanied by the deposition of carbon which may return to the gas phase as carbon monoxide, remain in the oxide film or dissolve in the metal. Isotopic tracer techniques wi

Electron microscope microprobe analysis (EMMA) has been applied to the determination of the elemental compositions of the kaolinite particles (Mg, A1, Si, K, Ti and Fe) contained in the 0.~0-3 Izm e.s.d., the 0.9-1.0/~m e.s.d, and the 1.9-2.0/am e.s.

The main commercially important kaolin resources are the primary deposits in Cornwall and the sedimentary deposits in South Carolina and Georgia in the U.S.A. Annual world production is about 18 Mt (1 t = 10 3 kg). In 1981 the U.K. production was 2.6

The adsorption of silicic acid on gibbsite (BET nitrogen area, 7.4 m2/g) suspended in NaCl solution (typically 10−2 M) has been measured over the pH range 4 to 11. For a fixed starting concentration of silicic acid, adsorption increased with increa

The quartz contents (maximum, 4 wt.%) of four clay materials and a tourmaline were determined by differential thermal analysis, by X-ray diffraction and by chemical analysis. The results are used to make a critical comparison of these three methods.

The choice of kaolinite sample for surface chemical studies is examined. An adsorption apparatus, particularly suited for those studies where the adsorbate acts as a deflocculant, is described. Some preliminary results are given for the adsorption of

In quantitative electron microscope microprobe analysis using the 'ratio method', standards containing known relative amounts of two or more of the sought elements are required. Techniques are described for the preparation of such standards using sui

The densities of kaolin—water suspensions have been measured using a pycnometric method at solids contents up to 60 wt%. The apparent molar volume of the clay was 196.0 ± 0.3 ml/mole (95% confidence limits) and independent of suspension concentrat
