The alkali and alkaline earth
metal carbonates have a positive effect on the cracking of oxygen-containing functional groups in oil shale.
3+] ions depending on the type of the alkaline earth
cation in the host composition, site-selective spectroscopy studies were performed for the series of [Eu.
Another characteristic feature is that the changes in the levels of the alkaline earth
metals can be correlated with the Ksp of their carbonates (De Visscher et al.

chromate by time-of-flight laser microprobe mass spectrometry and fourier transform ion cyclotron resonance mass spectrometry", International Journal of Mass Spectrometry, 198 (3), 189 - 211 (2000).
While previous biomass products have been rich in alkali and alkaline earth
metals that damage pipes, the researchers' biofuel product has fewer corrosive materials, making them ideal candidates for use in power plants.
They are lead based glazes, alkaline based glazes containing feldspars and/or frits, and alkaline earth
based glazes containing calcium, magnesium, barium, strontium, beryllium oxide, zinc oxide, cadmium oxide and bismuth oxide.
Rare earth and alkaline earth
metal borides belong to the group of nonoxide type metal-like compounds and have high melting point, high chemical stability, stable specific resistance, low expansion coefficient at certain temperature ranges, diverse magnetic orders, and high neutron absorbability [1,2].
Similarly, alabaster, plumbum, zings and mines of alkaline earth
metal exists in Dishu, another border district of the province, which is 215 kilometres to the south of Lashkargah.
Key observations are (a) the enhancement in stability observed when molecular NO2 is added pair-wise to an MgO (001) surface , and similar features observed for the BaO (100) substrate , which combined provide a possible comprehensive mechanistic understanding of the NO2 storage in alkaline earth
The contents include sections on each of the elemental groups, including the main groups (or families), alkali metals, alkaline earth
metals, halogens, and noble gases.
Radium is an almost pure-white alkaline earth
metal but it oxidises on exposure to air, becoming black.
In certain embodiments, the present invention is directed to the deposition of a zirconium-based pretreatment composition onto a substrate with the subsequent deposition of an electrodepositable coating composition, which comprises a soluble alkaline earth
metal ion, onto the pretreatment composition.
Morgan Thermal Ceramics' Superwool products are special low bio-persistent alkaline earth
composition fibers that have been uniquely engineered to offer advantages in high temperature insulation applications.
30 Cheltenham A white alkaline earth
metal with the atomic number 88 and chemical symbol Ra, radium was discovered by Marie and Pierre Curie in 1898.
The plot of chemical data on Trilinear diagram reveals that majority of the groundwater fall in the fields of 1, 3, 5 suggesting that alkaline earth
exceeds alkalies and weak acids exceeds strong acids respectively (Fig 2a and 2b).
