Using a NDJ-1 rotational viscometer and an AR500 rheometer, both static and dynamic viscosities of sodium silicate solutions were measured with changes of concentration, temperature, modulus (molar ratio of SiO 2 to Na 2 O), shear rate and chemical additives. Static results show that viscosity increases monotonously with concentration varying from 15 to 55%, decreases with temperature rising from 15 to 70 °C, and has a minimum value at a modulus of about 1.8. Measured data can be fitted quantitatively either by the Krieger-Dougherty expression or the Arrhenius equation with good agreement. This fact suggests that the sodium silicate solutions exhibit the properties of a suspension, in which the silicate anions, mainly constructed of Q 1 and Q 2 groups, act as a binder; the colloidal particles mainly constructed of Q 3 and Q 4 groups and small cations, act as effective rigid particles. Dynamic results show a shear thickening property in the high shear-rate regime, and a Newtonian property in the low shear-rate regime.

Journal of Solution Chemistry

溶液化学杂志为物理化学、化学物理、分子生物学、统计力学、生物化学和生物物理学等领域的液体溶液物理化学研究提供了一个论坛。重点是溶剂起主导作用而非偶然作用的论文。特色主题包括对液体溶液中电解质和非电解质的介电、光谱、热力学、传输或弛豫特性的实验研究。

The Journal of Solution Chemistry provides a forum for research in the physical chemistry of liquid solutions across various fields, including physical chemistry, chemical physics, molecular biology, statistical mechanics, biochemistry, and biophysics. The journal emphasizes papers where the solvent plays a dominant role rather than a coincidental one. Featured topics include experimental studies of dielectric, spectral, thermodynamic, transport, or relaxation properties of electrolytes and non-electrolytes in liquid solutions.
