The direct synthesis of a borosilicate version of SSZ-31 was investigated starting from fumed silica and sodium borate as the silicon and boron source, respectively. As-synthesized boron Beta as a seed material was required for synthesizing fully crystalline material. The synthesis vessel has been observed to play a major role during the …

A modified calcium silicate borate (Ca11Si4B2O22) ceramic was prepared using the eutectic component of sodium metaborate (NaBO2) by the melt quenching method at 950 °C, suggesting that sodium metaborate could be a suitable flux for the synthesis of glass-ceramic materials.

Bioactive glasses are degradable, biocompatible glasses, which form a resilient bond with the host tissue. This material is osteoconductive and stimulates bone regeneration. These glasses are composed of silica, sodium oxide, calcium oxide, and phosphate. The compositions can be altered to incorporate different ions in their …

recommended for older systems which suffer from corrosion Borate-nitrite formulations provide corrosion protection which is equal to the old chromate products which were abandoned for environmental reasons. The sodium tetraborate component creates a buffer in the system that stabilizes the pH between 9.0 and 9.5.

Here, we report on the influence of borate additives on the structure and properties of partially hydrolysed PVAc. In addition to the general crosslinking function of borate additives, an extraordinary plasticizing …

A calculation-graphic analysis of the IR spectra of sodium borate and silicate as components of a glass batch, obtained in aqueous medium, and probable contaminants — boric and silicic acids — was conducted.
