Calcium-Deprived Rats Avoid Sweet Compounds
The Journal of Nutrition, 1998To characterize the link between calcium status and sweet solution intake, rats fed a diet containing 25 mmol Ca2+/kg (Ca-25, low calcium) or 150 mmol Ca2+/kg (Ca-150, control) were given 48-h two-bottle tests with a choice between water and various concentrations of a nutrient (sucrose, Polycose, ethanol and/or corn oil).

The chemical element calcium, Ca, atomic number 20, is an alkaline-earth metal which is fifth in abundance among all elements (ca 4%) and the third most abundant metal found in the earth's crust. It is too reactive to be found naturally in the free state, but its compounds are widespread as the minerals marble, CaCO3, limestone, CaCO3, calcite, CaCO3 ...

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.

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.

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 ...

XPS study of some calcium compounds
Journal of Materials Processing Technology, 1995Abstract X-Ray Photoelectron Spectroscopy (XPS) photoemission lines of some calcium compounds have been measured. The fine structure and position of the Ca 2 p 3 2 line is discussed. The Wagner diagram of the oxygen KLL transitions is presented. The surface composition of some compounds is calculated.

Superconducting graphite intercalation compounds with calcium
Solid State Sciences, 2008"In the graphite-lithium-calcium system, four well-defined intercalation compounds were synthesised. Two of them, CaC6 and Li3Ca2C6, exhibit superconducting properties at 11.5 K and 11.15 K, respectively, the highest critical temperatures among those of graphite intercalation compounds.

Calcium Reduction of Zirconium Oxide Compounds
Inorganic Materials, 2020We have determined the adiabatic temperature of the calcium reduction of ZrO2 and CaZrO3 (1525 and 1040 K, respectively) and the reaction onset temperature. In a mixture of reagents under an argon atmosphere in a reactor, it is about 1123 K and is determined by the calcium melting onset. If calcium particles with CaCl2 film on their surface are used as

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 ...
