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.

| Product Code | NCZ-C-102/20 |
| CAS Number | 12604-56-7 |
Application of Ferro Titanium carbide powder:
In the present study, Fe-based hardfacing coating reinforced by TiC particles was obtained by manual shielded metal arc welding (SMAW) in which H08A bare electrode was coated with fluxes, to which different measures of ferrotitanium, rutile, graphite, calcium carbonate, and calcium fluoride had been added.
The microstructure and wear properties of the hardfacing coating were studied through scanning electron microscopy (SEM), transmission electron microscopy (TEM), an X-ray diffractometer (XRD), and a wear test.
The results indicate that TiC particles are produced by a direct metallurgical reaction between ferrotitanium and graphite during welding.
TiC particles are uniformly dispersed in the matrix of lath martensite and retained austenite with particle sizes in the range of 3–5 μm. Fe-based hardfacing coating reinforced by TiC particles is found to possess better wear resistance and a lower coefficient of friction than that of the AISI 1045 steel substrate.

Brief Description of WC Tungsten Carbide Powder
Tungsten carbide powder (chemical formula: WC ) is a chemical compound (specifically, a carbide ) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine Gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry. Physical Properties of WC Tungsten Carbide Powder Tungsten carbide has a high melting point at 2,870 °C (5,200 °F), a boiling point of 6,000 °C (10,830 °F) when under a pressure equivalent to 1 standard atmosphere (100 kPa), the thermal conductivity of 110 W·m−1·K−1, and a coefficient of thermal expansion of 5.5 µm·m−1·K−1. Tungsten carbide is extremely hard, ranking about 9 on Mohs scale, and with a Vickers number of around 2600. It has Young’s modulus of approximately 530–700 GPa, a bulk modulus of 630–655 GPa, and a shear modulus of 274 GPa. It has an ultimate tensile strength of 344 MPa, the ultimate compression strength of about 2.7 GPa and a Poisson’s ratio of 0.31. Chemical Properties of WC Tungsten Carbide Powder There are two well-characterized compounds of tungsten and carbon, WC and tungsten semi abide, W2C. Both compounds may be present in coatings and the proportions can depend on the coating method. At high temperatures, WC decomposes to tungsten and carbon and this can occur during high-temperature thermal spray, e.g., in high-velocity oxygen fuel (HVOF) and high energy plasma (HEP) methods.Application of WC Tungsten Carbide Powder
