General description
Drying pearls Orange (Silica gel orange), commonly used as a drying agent in laboratories, is suitable for drying all gases and solids. It is used in desiccators, drying towers, and absorption tubes. Silica gel orange provides longer storage conditions due to its large surface area which enables high absorption capacity. It also changes its color from orange to colorless after moisture absorption (approx. 6 wt% load).
Preparation Note
regeneration by drying at 130 - 160 °C; do not heat above 160 °C
Storage Class
13 - Non Combustible Solids

The low solubility (high durability) of yttrium aluminosilicate (YAS) glass is one of its most important properties for use in in situ radiotherapy. Simple parameters, such as silica or yttria content or network connectivity, are not sufficient to rationalize the

Ceramic silica (SiO(2)) hybrid nanofibers were prepared by electrospinning of solutions containing biocompatible polymer and modified silica precursors. The new hybrid nanofibers are based on polyethylene oxide (PEO) and a new solution of modified sol-gel particles of mixture containing tetraethoxysilane

Sugar molecules adsorbed at hydrated inorganic oxide surfaces occur ubiquitously in nature and in technologically important materials and processes, including marine biomineralization, cement hydration, corrosion inhibition, bioadhesion, and bone resorption. Among these examples, surprisingly diverse hydration behaviors are observed for
