Silicate Pneumoconiosis in Hens
Journal of Comparative Pathology, 2000Thirteen cases of silicate pneumoconiosis in 3- to 4-year-old hens are described. Ten of the birds were raised in the suburbs of a city near several chalk quarries and two cement-works; the remaining three hens (aged 3 years) had lived in an environment with high particulate pollution from a nearby brick-works in which large amounts of clay were used ...

Minerals which are not silicates have been grouped together in this chapter for the description of their properties. However, unlike the silicates, the crystal structures and chemical variation of members of the group are not easily related to mineralogical properties and the mode of occurrence. Even subdivision of the group into transparent and opaque

Aqueous Silicic Acid, Silicates and Silicate Complexes
1978The paper aims at giving a brief review of the aqueous chemistry of silicic acid, silicates and silicate complexes. In particular, problems concerning equilibria and structures are discussed. In addition geochemical data of silicon and silicon distribution on the earth crust will be briefly presented.

Viscosity of liquid silica, silicates and alumino-silicates
Geochimica et Cosmochimica Acta, 1982Viscosity measurements are reported for amorphous silica and liquids belonging to the systems SiO2-M, SiO2-Al2O3-M, where M is an alkali-earth metal oxide, MnO, or alumina, and the systems SiO2-“FeO”, SiO2-FeO-Fe2O3-CaO, and SiO2-Al2O3-N, where N = Na2O or K2O.

Structure of Calcium Silicate Hydrate (C‐S‐H): Near‐, Mid‐, and Far‐Infrared Spectroscopy
, 2004The mid-, near-, and far-infrared (IR) spectra of synthetic, single-phase calcium silicate hydrates (C-S-H) with Ca/Si ratios (C/S) of 0.41–1.85, 1.4 nm tobermorite, 1.1 nm tobermorite, and jennite confirm the similarity of the structure of these phases ...

Derivatives of silicic acids as model compounds for silicates
Physics and Chemistry of Minerals, 1988Silicon-29 chemical shifts of methyl, ethyl, chloro and trimethylsilyl derivatives of silicic acids are compared to those of silicic acid anions found in aqueous solutions. Although the chemical shifts of the silicate anions vary with pH and concentration, a good correlation is obtained for the chloro and alkoxi derivatives.
