These units may be present in many structural groups such as diborate
, tetraborate, pentaborate or broxol ring etc based on the percent of bridging or non-bridging oxygens in the glassy network .
In [3-5], however, it was noted that the scale of the short range order does not reflect all the complexity of borate glasses, whose structure is characterized by the presence of the so-called superstructural units (boroxol rings, triborate rings, pentaborate groups, diborate
groups, etc.) in the next hierarchical level (intermediate range order (IRO)).
The formation of calcium diborate
([CBH.sub.6]) barrier layers on the particle surfaces could be delayed to reach the optimum setting times and strength at a convenient [B.sub.2][O.sub.3] concentration .
composition [B.sub.3] and [B.sub.4] concentrations are equivalent, and the corresponding mole fraction of the alkali oxide is 0.33.
Bochmann, "The synthesis of new weakly coordinating diborate
anions: anion stability as a function of linker structure and steric bulk," Dalton Transactions, no.
This peak was present due to the diborate
linkage, B-O-B, in the borate glassy network.
The borate matrix possesses well defined gathering of B[O.sub.3] triangles and B[O.sub.4] tetrahedra to form stable borate groups such as diborate
, triborate, and tetraborate .
: crystal structure, magnetization, and thermal extinction dependence.
Finally, the company is also working on sodium borohydride and titanium diborate
batteries that promise substantially longer lifetimes compared to conventional zinc-based batteries.
Melamine crystal and other products such as melamine cyanurate, melamine phosphate, dimelamine phosphate and melamine diborate
used in flame-retardant systems for plastics, coatings, elastomers, and foams.
In addition, the additional modifier oxide causes a progressive change of some B[O.sub.3] triangles to B[O.sub.4] tetrahedra, resulting in the formation of various cyclic units including diborate
, triborate, tetraborate, or pentaborate groups .
Not yet commercially available is melamine diborate
, which has flame-retardant and smoke-suppressant properties, giving it potential in cable applications.
