The first example of a microporous framework potassium hafnium silicate (AV-12, Aveiro microporous solid no. 12) with a known structure is reported. AV-12 and the rare potassium zirconium silicate mineral umbite possess similar structures, composed of corner sharing MO_6 octahedra and SiO_4 ...
nepheline, aegirine, apatite, Ti–rich magnetite, plus abundant calcite and some K-feldspar and zeolites. (3) A coarse-grained rock is composed of calcite plus intergranular glauconite, a mixture of spinel mineral group and Ti–rich magnetite, accessory barite, pyrite, and chabazite-K. The ig...
aThis approach resulted in four mineral coal types (silicate, silicate–carbonate, silicate–sulphide, and silicate–sulphide–carbonate or mixed) further divided into seven subtypes (with high, medium and low detrital tendencies) based on the sum of silicates and oxyhydroxides. [translate] a亚洲...

A rubber cement is prepared by mixing 100 parts of a polymerization product of a conjugated diolefin having not in excess of 8 carbon atoms which has a raw computed Mooney plasticity of at least 90 and is compatible with hydrocarbon mineral oils with x parts of compatible tackifying resinous ...
migmatite gneisses as greasy, green patches with diffuse margins (‘patchy charnockite’). Bands of migmatized mafic granulites, metapelitic rocks (infrequently sapphirine-bearing) and rare calcsilicate granulites, besides isolated appearance blastoporphyritic charnockite, occur congruently with the ...
Structure determination of the blue mineral pigment aerinite from synchrotron powder diffraction data The structure of aerinite, a blue fibrous silicate mineral associated with the alteration of ophitic rocks in the southern Pyrenees, has been determined by...

The silicifiable potassium water glass facilitates uniform wettability of the substrate and a chemical reaction that firms and consolidates the mineral substrate. -Intermediate and top coat with BEECK – BEECKOSIL, Coarse and Fine This solvent-free 1 pack silicate system sil...
Orientation and elongation distributions of carbonate and tectosilicate grains measured on mineral maps reveal an anisotropic mesostructure relative to the bedding plane, in agreement with the geological history of the sedimentary rock. Diffusion simulations were performed based on the 3-D mineral maps ...
