The peaks which could be ascribed to alkaline Earth metal species for all tested samples are not observed, what is probably related with good dispersion of the alkaline Earth metals in the zeolite as a result of their reaction with silanol groups of vacant T-atom sites and/or ion exchange with a proton of HAlBeta.
As aforementioned, this is likely related to the fact that NiNP affects carbonic acid formation and dissociation but does not affect the dissolution or precipitation of alkaline earth metal cations.
Alkali and alkaline earth metal cations affect reactivity of oil shales, and leaching of these mineral matters with HCl slightly decreases oil shale conversion to volatile hydrocarbons and affects the reactivity of organic matter at pyrolysis.
This alkaline earth metal has eight more protons than magnesium.
Other topics include wrought magnesium research for automotive applications, the mechanical properties of superlight Mg- Li-Zn alloys, the dissolution and recovery of manganese additions into liquid magnesium, and the effect of alkaline earth metal oxides on magnesium alloys.
[USPRwire, Thu Jul 18 2019] Calcium is an alkaline earth metal and a chemical element with characteristics similar to barium and strontium.

Active ingredients which can load on the carrier include alkali metal, alkaline earth metal, transition metal oxides, rare earth metal oxides, mixed metal oxide, and nanoscale metal oxides.
The composition does not contain gluconic acid, ethylene diaminetetraacetate sodium salt, 5-bromo-5-nitro-1,3dioxane, any abrasives, silicas, alkaline earth metal carbonates, alkyl glycine surfactants, cyclic imidinium surfactants, alkali metal carbonates or more than 3% by weight of a fatty acid or salt.
A process for the production of an alloy of cross-linked or partially cross-linked rubbers and aromatic polyesters, wherein a mixture of a rubber latex and an aqueous solution of an alkali metal diphenolate or an alkaline earth metal diphenolate is reacted with a solution of a dicarboxylic acid halide and/or a carbonyl halide in a water-immiscible solvent, an aromatic polyester forming at the phase boundary of water/organic solvent, which polyester goes over into the organic phase, and the rubber at the same time going from the aqueous phase into the organic phase, and the organic phase is then separated and the organic solvent is removed.
But this alkaline earth metal is more commonly found in compounds (two or more elements that are chemically combined).
