Zinc borate is an important boron compound that can be used as multi-functional flame retardant additive due to its high dehydration temperature property. In this study, the raw materials of ZnSO4.7H2O, NaOH and H3BO3 were characterized by X-Ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FT-IR) and used in the synthesis of zinc borates. The synthesis parameters were set to 1...
Magnesium wastes and scraps, one of the metal wastes, are produced by many industrial activities, all over the world. Their growing size is becoming a future problem for the world. In this study, the use of magnesium wastes as a raw material in the production of the magnesium borate hydrates are aimed. The method used in the experiments is hydrothermal synthesis. The conditions are set to, wast...
Dehydration behavior gives a hint about thermal properties of materials. It is important for the usage areas and transportation of minerals. Magnesium borates can be used as additive materials in areas such as in the production of superconducting materials, in the composition of detergents, due to the content of boron in the friction-reducing additives in oils and insulating coating composition...
The first all-alkaline-earth beryllium borate with fluorine anions, Ca3Be6B5O16F, was synthesized by a spontaneous crystallization flux method using LiF-B2O3 as the flux. The structural framework of Ca3Be6B5O16F is composed of the inter-connected [Be6B3O16] and [BO3] fundamental building blocks, with [CaO7F] distorted polyhedra located in the interstitial sites. The [Be6B3O16] group is discover...
Preparation ofα-Bromoketones Involving the Reaction of Enol Triethyl Borates with N-Bromosuccinimide
Nano particles of zinc borate were obtained by homogeneous precipitation method which is based on dissolving in ammonia and precipitating it as nano slow evaporation ammonia. The synthesized borates characterized advanced analytical techniques. Zinc used a lubricant additive to spindle oil having Span 60 dispersant. well dispersed shown optical microscopy the oils. Four ball tests lubricants in...
High-pressure X-ray diffraction studies on nanocrystals of the GdBO3 and YBO3 rare-earth orthoborates are herein reported up to 17.4(2) 13.4(2) GPa respectively. The subsequent determination room-temperature pressure-volume equations state is presented discussed in context contemporary publications which contradict findings this work. In particular, isothermal bulk moduli found be 170(13) 163(1...
