The method of trimethylsilylation was used to study anion distributions in sodium silicate solutions with Na2O: SiO2 ratios of 1:1 and 1:3.41 at various concentrations. The polysiloxanes produced were characterised, mainly by g.l.c., g.p.c. and C and

The effects of adding glyoxal to sodium silicate solutions have been investigated and compared with those of adding glycollic acid or hydrochloric acid: gel-time and the proportions of small silicate units in the solutions were both studied. It is co

Dehydroxylation of ettringite in an atmosphere of constant partial water vapour pressure (30–400 Torr) and controlled temperature (55–95 °C) yields an X-ray amorphous product containing 11–13 H 2 O per ettringite formula unit. The X-ray amorph

Selected area electron diffraction studies of ettringite, carbonate ettringite and thaumasite have been made. Ettringite suffers severe dehydration effects in the electron microscope whereas carbonate ettringite and thaumasite are relatively stable a

Solid solutions between thaumasite and ettringite were prepared by methods analogous to those well established for the preparation of thaumasite and ettringite. The extent of immiscibility in this system is investigated by varying the Al:Si and SO42

The excellent properties of α-Al2O 3 are extremely dependent on the microstructural characteristics of the ceramic materials, which stress out the importance of designing new processing routes and/or improving the existing ones to reach a rigorous m

The reaction of MII acetate (M = Sr or Ba) with benzene-1,3,5-tricarboxylic acid (H3btc) yielded crystals of formulae [M(Hbtc)(H2O)2]·0.5H2O. These compounds are isostructural as shown by X-ray single-crystal analysis and by X-ray powder diffraction

Because the durability of high-performance cements is as important as their strength, the performance of pore-reduced cement (PRC) in aggressive media such as sulfuric, hydrochloric and ethanoic acids, was studied and compared with that of ordinary P
