The number of monovalent cations in 32‐cation formulas follows linear dependences on the average cation valence e / c and on the 16‐unit parameters 2 m 4 n , showing that, except alkali‐free glasses, the compositions of soda–silicate glasses converge to 2 N 2 + N 3 ≈ 8, where N...

The thermal conductivities of some silicate glasses have been investigated by a steady-state method at 30°C. Experimental results show that the thermal conductivity progressively decreases with the increase of the formula weight of the R 2O component. The effects of composition and structure on the...
H2O/R2O has no influence on the molecular structure of the aluminosilicate. Aluminium in the aluminosilicate is four-fold coordinated for the whole range of silicate solutions investigated. Moreover, Si and Al are homogeneously distributed and the ratio Al/Si in the aluminosilicate is the same ...

1. A composition for use in cladding metal, the composition comprising: a frit mixture; a wetting agent consisting of one or more of water and ethanol; a colloidal and/or liquid sodium silicate in the amount of approximately 1-20% by volume of the wetting agent; and/or a colloidal and/...
A thermosetting resin composition comprising (A) the hydrolysate of an alkoxysilane represented by either of the general formulas: ##STR1## wherein R.sup.1 and R.sup.2 are respectively a divalent group, R.sup.3 is a lower alkyl and R.sup.4 is R.sup.3 or
(SiO2), an oxide form of the element silicon. In fact, so common is the use of silicate minerals that traditional ceramics are often referred to as silicate ceramics, and their manufacture is often called the silicateindustry. Many of the silicate materials are actually unmodified or chemically...
