It has been found that titanium oxides were TiO monoclinic, Ti 4 O 7 anorthic and TiO 2 orthogonal structure in one nanometer inclusion, as the composite oxide was precipitated MnS/FeS 2 cubic structure during sub-rapid solidification. Thermodynamic calculation analysis showed that it was ...
A 'Non-Metallic Mineral' refers to minerals that do not contain metal elements and are commonly used in construction, with mineral aggregates like sand, gravel, and crushed stone being the largest component of this category. AI generated definition based on: The Extractive Industries and Society,...
Among the group of compounds composed of the amorphous oxides and chalcogenides, amorphous oxides and chalcogenides of semi-metallic elements are more preferred, and oxides and chalcogenides formed from one kind alone or combinations of two or more kinds of the elements of Group 13 (IIIB) to Grou...
Researchers have found a new path by suspending nano-sized metallic or metal oxides solid materials in the host-liquids where an increment of thermal conductivity was conducted. This idea gave rise to the nascence of the so-called “Nanofluid”. Nanofluids are usual liquids that contain usually ...
“Corrosion inhibitive” refers to a composition or coating that when deposited onto a metallic substrate provides a coating that resists, prevents, or slows the alteration or degradation of the substrate such as by chemical or electrochemical oxidizing processes. A corrosion inhibitive composition or ...
Hydroxylation of arenes via activation of aromatic Csp2–H bond has attracted great attention for decades but remains a huge challenge. Herein, we achieve the ring hydroxylation of various arenes with stoichiometric hydrogen peroxide (H2O2) into the corr

Oxides are particularly difficult. Consider, for example, the oxides of the period 2 elements: Li, Be, B, C, N, O, F & Ne. According to webelements, the set of period 2 oxides consists of:This set of chemical compounds clearly presents as an unpredictable "broken terrain". It is ...
Method of molding nonplastic metallic oxidesKOHL HANSREICHMANN REINHOLD
A process for moulding non-plastic metallic oxides, e.g magnesium oxide, beryllium oxide, zirconium oxide, aluminium oxide, or mixtures thereof, consists in calcining the oxide to incipient crystallization, grinding to a size of grain of about 2-15 m , deflocculating by adding dilute acid, e...
