In recent years, the industrial use and importance of boron compounds has further increased with the potential application of boron as hydrogen carrier in the form of BH4 in the exploitation of hydrogen as clean energy. Boron compounds can be produced from a variety of boron minerals and boronrich brines. Colemanite (Ca2B6O11.5H2O), ulexite (NaCaB5O6(OH)6.5H2O) and borax (Na2B4O5(OH)4.8H2O) are...

Pyrolysis of Alcea pallida stems was performed in a fixed-bed tubular reactor with and without catalyst at three different temperatures. The effects of pyrolysis parameters including temperature and catalyst on the product yields were investigated. It was found that higher temperature resulted in lower liquid (bio-oil) and solid (bio-char) yields and higher gas yields. Catalysts had different e...

In this research, composite material has been obtained by reinforcing colemanite, ulexite, and tincal ore from the boron factory to unsaturated polyester. The effects of these fillers, which are used in different ratios mass, on density, Shore D hardness, thermal conductivity coefficient, stability polyester have investigated. According results obtained, as mass ratio components mixture raised,...

The soils surrounding energy geo-structures are exposed to high temperatures and temperature cycles. Changes in the engineering properties of should be investigated under thermal effects that highly durable against changes needed for thermo-active geo-structures. Generally, bentonite or sand–bentonite mixtures (SBMs) preferred as natural barrier soil materials. Hence, these materials improved. ...

In this study, heat treatment was applied to the CMAS parent glass produced using brucite with calcite, kaolin, ulexite natural raw materials and commercial MgF2, considering DTA measurements. The crystallization behaviour growth directions of crystals were investigated. XRD SEM investigations revealed that anorthite formed during treatment, ceramic obtained in CAS system by surface crystalliza...
