Gelling properties of sepiolite versus montmorillonite
TL;DR: In this paper, the gelling properties of four different sources of sepiolites were compared with a Na-montmorillonite from Wyoming, based on ease of gel preparation, gel viscosity and yield stress, and the modulus of rupture of slip cast bars made with kaolinite.
Cation-Exchange Properties of (Al + Na)-Substituted Synthetic Tobermorites
TL;DR: Tobermorite, a hydrous calcium silicate that has a layer-type of structure similar to that of the 2:l clay minerals, exhibits reversible alkali cation exchange and selective cesium uptake upon a coupled substitution of (Al 3 § + Na § for Si 4+. Substituted tobermorites were synthesized using aluminosilicate gels, NaOH, and CaO, in Parr bombs at 175~ for 4 days as mentioned in this paper.
Test of the applicability of the Clapeyron relationship to a few cases of solid-solid transitions
A. J. Majumdar,Rustum Roy +1 more
TL;DR: In this article, the general applicability of the Clapeyron relation to polymorphic transformations of several types has been tested experimentally on the transitions in CsCl, NH4Cl and NH4NO3, Na3AlF6 and GeO2.
Microwave-induced reaction sintering of NiAl2O4
TL;DR: In this article, the authors reported the simultaneous synthesis and sintering of NiAl 2 O 4 from NiO + Al 2 O 3 powder mixture in just 15 min in a 2.45 GHz microwave field.
Thermal-expansion materials not so new
Rustum Roy,Dinesh K. Agrawal +1 more
TL;DR: In this paper, Cahn et al. concluded that the phase ZrW2O8 has a negative thermal expansion, which is not novel: this phase is one of many known for decades to exhibit the phenomenon.
