Salen-Type Compounds of Calcium and Strontium
Inorganic Chemistry, 2002Salen complexes of the heavy alkaline-earth metals, calcium and strontium, were prepared by the reaction of various salen(t-Bu)H(2) ligands with the metals in ethanol. Six new calcium and strontium compounds, [Ca(salen(t-Bu))(HOEt)(2)(thf)] (1), [Ca(salen(t-Bu))(HOEt)(2)] (2), [Ca(salpen(t-Bu))(HOEt)(3)] (3), [Ca(salophen(t-Bu))(HOEt)(thf)] (4), [Sr ...

The alkalizing properties of calcium hydroxide compounds
Dental Traumatology, 1989Abstract Calcium hydroxide compounds are available in various forms, such as in aqueous suspensions or as cements, liners, pastes or filled resins. When such compounds are exposed to water, the calcium hydroxide dissociates and the pH value shifts to the basic.

Adjuvant Properties of Aluminum and Calcium Compounds
1995It is likely that aluminum compounds will continue to be used with human vaccines for many years as a result of their excellent track record of safety and adjuvanticity with a variety of antigens. For infections that can be prevented by induction of serum antibodies, aluminum adjuvants formulated under optimal conditions are the adjuvants of choice. It

Calcium Fluosilicate Compound is not Calcium Fluosilicate
Journal of Economic Entomology, 1932The difference between true calcium fluosilicate and “calcium fluosilicate compound” is pointed out. It should be remembered that entomological results obtained with these materials should be reported separately and should not be compared as they are very much different in chemical composition. Analyses and compositions of these materials are shown.

CRYSTALS OF CALCIUM COMPOUNDS IN GRAMINEAE
New Phytologist, 1983SummaryFrom reviews of the anatomy and cell contents of grasses it would appear that crystals of calcium compounds do not occur. However, 13 scattered reports of such crystals in grasses have been discovered in the literature. As a result of observations made by the author, calcium oxalate crystals have been found in bundle sheath cells and adjacent ...

Calcium Complexing by Phosphorus Compounds
1969The ability of the polyphosphates to form water-soluble complexes with calcium has been known for a long time. The phenomenon of binding alkaline earth ions in soluble complexes, and thus preventing the formation of undesirable precipitates, is generally called “sequestration.” This was the subject of earlier patent literature.1 The role of these ...
