The structural characteristics of all the borates available were analyzed using the Inorganic Crystal Structure Database. The fundamental building blocks (FBBs) in 841 borates were systematically classified into 6 types in terms of their topological structures. By including the polymerization of the FBBs in the borate structure, a novel systematic classification and an algebraic description of ...

In the present study the thermal structure evolution is reviewed for known nonlinear optical borates such as β-BaB2O4, LiB3O5, CsLiB6O10, Li2B4O7, K2Al2B2O7, and α-BiB3O6, based on single-crystal and powder X-ray diffraction data collected over wide temperature ranges. Temperature-dependent measurements of further borates are presented for the first time: α-BaB2O4 (295–673 K), β-BaB2O4 (98–693 ...

Borates have played an ever-increasing role in the preservation of wood worldwide and especially in the USA since the voluntary cancellation of CCA for residential lumber use patterns in 2004. However, there has not been a review of the efficacy and performance of borates, especially Disodium Octaborate Tetrahydrate, outside of the AWPA Data Package submitted by Nicholas and Preston in 1988 and...

New aryl- and heteroarylboronate esters chelated by dipropanolamine are synthesised directly from boronic acids. The corresponding anionic borates are readily accessible by deprotonation and demonstrate an increase in hydrocarbyl nucleophilicity in comparison to other common borates. The new borates proved competent for magnesium or zinc additive-free, direct boron-to-iron hydrocarbyl transmeta...

Abstract—Boron-gypsum is a waste which occurs in the boric acid production process. In this study, the boron content of this waste is evaluated for the use in synthesis of magnesium borates and such evaluation of this kind of waste is useful more than storage or disposal. Magnesium borates, which are a sub-class of boron minerals, are useful additive materials for the industries due to their re...

Waste problem is becoming a future problem all over the world. Magnesium wastes which can be used in recycling processes are produced by many industrial activities. Magnesium borates which have useful properties such as; high heat resistance, corrosion resistance, supermechanical strength, superinsulation, light weight, high coefficient of elasticity and so on. Addition, magnesium borates have ...

Turkey has 72 % of total world boron reserves on the basis of B2O3.Borates that is a refined form of boron minerals have a wide range of applications. Zinc borates can be used as multifunctional synergistic additives. The most important properties are low solubility in water and high dehydration temperature. Zinc borates dehydrate above 290°C and anhydrous zinc borate has thermal resistance abo...

The structural aspects of xCs2O-(1-x)B2O3 glasses have been investigated by molecular dynamics as functions of Cs2O content (x=0.2, 0.3, and 0.4) and temperature (T=300 and 1250 K). The tetrahedral (BØ4-) and triangular (BØ3,BØ2O-, and BØO2 (2-)) short-range order borate units were found to be the structure-building entities of the simulated glasses [Ø=bridging oxygen (BO) and O-=nonbridging ox...

In this paper we re-examine the alkali dependence of the fraction of four-coordinated borons (N4) in two series of glasses: alkali borates (0·4M2O.B2O3) and mixed lithium caesium borates (0·4(xLi2O+(1-x)Cs2O). B2O3). High field B MAS-NMR experiments were performed to maximise the accuracy of the present results. We found no evidence for an alkali dependence on N4 in either system. In each case ...
