MICROSTRUCTURE AND PROPERTIES OF COLLOIDAL SILICA BONDED MAGNESITE CASTABLE REFRACTORIES

Abstract: Efforts have been carried out in order to use microsilica to develop a forsterite bond rather than other types of binders in the basic refractory castables. According to the higher drying rate and sinterability of colloidal silica, it has been proposed in the recent years. In the present work, effects of replacement of microsilica by colloidal silica evolution of forsterite bond have ...

Cluster formation in polyelectrolyte-micelle complex coacervation.

The temperature-induced liquid-liquid phase transition (complex coacervation) of a polycation-anionic/nonionic mixed micelle system was examined over a range of macroion concentrations and polycation molecular weights (MW) using turbidimetry and dynamic light scattering (DLS). DLS revealed a progressive increase in complex/aggregate size with temperature up to the phase transition at T(φ), foll...

Complex coacervation of supercharged proteins with polyelectrolytes.

Complexation of proteins with polyelectrolytes or block copolymers can lead to phase separation to generate a coacervate phase or self-assembly of coacervate core micelles. However, many proteins do not coacervate at conditions near neutral pH and physiological ionic strength. Here, protein supercharging is used to systematically explore the effect of protein charge on the complex coacervation ...

Synthesis of colloidal silica dumbbells.

We describe the synthesis and characterization of stable suspensions of monodisperse fluorescently labeled silica dumbbell particles. Pure dispersions of silica dumbbells with center-to-center lengths from 174 nm to 2.3 microm were produced with a variety of aspect ratios. Individual particles in concentrated dispersions of these particles could be imaged with confocal microscopy. These particl...

Colloidal Silica and the Efficiency of Phosphates

General fertilizer practice recognizes in a vague way that there are reactions between soils and phosphatic fertilizers which affect the efficiency of the fertilizers. Bone meal, for instance, is recommended for use on open soils which are not too dry (39, p. 169), and for light soils not too deficient in phosphoric acid (3%, p. 320). Floats are recommended by Wheeler (39, p. 173) for acid soil...
