Boron trioxide Powder Description :
Boron trioxide Powder is one of the oxides of boron. It is a white, glassy solid with the formula B2O3.
It is almost always found as the vitreous (amorphous) form; however, it can be crystallized after extensive annealing (that is, under prolonged heat).
Glassy boron oxide (g-B2O3) is thought to be composed of boroxol rings which are six-membered rings composed of alternating 3-coordinate boron and 2-coordinate oxygen.
Because of the difficulty of building disordered models at the correct density with many boroxol rings, this view was initially controversial, but such models have recently been constructed and exhibit properties in excellent agreement with the experiment.
It is now recognized, from experimental and theoretical studies, that the fraction of boron atoms belonging to boroxol rings in glassy B2O3 is somewhere between 0.73 and 0.83, with 0.75 correspondings to a 1:1 ratio between the ring and non-ring units.
The number of boroxol rings decays in the liquid state with increasing temperature.
The crystalline form (α-B2O3) (see structure in the infobox) is exclusively composed of BO3 triangles. This trigonal, quartz-like network undergoes a coesite-like transformation to monoclinic β-B2O3 at several gigapascals (9.5 GPa).
Boron trioxide is produced by treating borax with sulfuric acid in a fusion furnace.
At temperatures above 750 °C, the molten boron oxide layer separates from sodium sulfate. It is then decanted, cooled, and obtained in 96–97% purity.
Another method is heating boric acid above ~300 °C. Boric acid will initially decompose into steam, (H2O(g)) and metaboric acid (HBO2) at around 170 °C and further heating above 300 °C will produce more steam and diboron trioxide. The reactions are:
H3BO3 → HBO2 + H2O
2 HBO2 → B2O3 + H2O
Boric acid goes to anhydrous microcrystalline B2O3 in a heated fluidized bed. A carefully controlled heating rate avoids gumming as water evolves.
Molten boron oxide attacks silicates. Internally graphitized tubes via acetylene thermal decomposition are passivated.
Crystallization of molten α-B2O3 at ambient pressure is strongly kinetically disfavored (compare liquid and crystal densities).
The threshold conditions for the crystallization of the amorphous solid are 10 kbar and ~200 °C.
Its proposed crystal structure in enantiomorphic space groups has been revised to enantiomorphic space groups P3121(#152); P3221(#154) (e.g., α-quartz).
Boron oxide will also form when diborane (B2H6) reacts with oxygen in the air or trace amounts of moisture.

Aluminum Diboride Powder RELATED INFORMATION
Aluminum boride is an ionic compound, with a hexagonal crystal structure. Aluminum boride at an absolute temperature slightly 40K (equivalent to -233 ℃) will be transformed into a superconductor. And its actual operating temperature is 20 ~ 30K. To reach this temperature, we can use liquid neon, liquid hydrogen, or closed-cycle refrigerator to finish cooling. Compared to the current industry using liquid helium to cool the niobium alloy (4K), these methods are simpler and more economical. Once it is doped with carbon or other impurities, magnesium diboride in a magnetic field, or there is a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better.
