... equilibrium hypothesis is discussed and justified for the present application. The only solid phases taken into account are portlandite [Ca(OH) 2 ] and calcium-silicate-hydrate (C-S-H). The model predicts the existence of an undamaged core separated from the free surface being attacked by a sharp portlandite...

... High-calcium quicklime [calcium oxide (CaO)] is presently the major chemical used for controlling environmental pollutants. Areas of application for water include domestic water, industrial waste water, including acid mine drainage, and sewage and hazardous wastes. Domestic water is included...

... To reduce excessive maintenance at a water softening plant due to scale buildup at meters and filter clogging, it was decided to carbonate the highly alkaline water. This paper reports the author's experiences in the carbonation of calcium and calcium hydroxide as well as magnesium and magnesium...

Numerous examples of methods developed employing the dissolution technique are cited, with data on accuracy and precision...

... Westinghouse has been conducting a program to upgrade the purity of primary-loop cooling water in pressurized water reactor (PWR) nuclear power plants, and a method was needed to measure cationic impurities such as calcium, magnesium, and aluminum in the 0 to 10-ppb range. After examination...

... Methods have been developed for the determination of aluminum, barium, calcium, lead, magnesium and silver in ferrous alloys and steels by flame emission and atomic absorption spectrometry. The samples are dissolved in a mixture of nitric, hydrochloric, hydrofluoric, and perchloric acids. Flame...

Of the embrittling metals, only cadmium is considered a likely contributor to the PCI (pellet-clad interaction...

..., it is shown that good inclusion shape control is obtained by simple additions of calcium silicon to the ladle. Various methods of evaluating transverse ductility in hot-rolled, high-strength, low-alloy (HSLA) steels are compared. A relationship is obtained between the ratio of transverse to longitudinal...

... The behavior of calcium has been investigated in the interference systems: hydrochloric acid/calcium, sodium chloride/calcium, acetic acid/calcium, aluminum/calcium, and phosphate/calcium. Possible mechanisms are detailed and corrective procedures tested. In general, presence of a concomitant...
