Technology Process of Tungsten diboride

There total 5 articles about Tungsten diboride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

boron + tungsten (7440-33-7) → tungsten diboride (12228-69-2)

Guidance literature:

in electric furnace in carbon crucible;

DOI:10.1039/CT9028100014

Reference yield:

magnesium diboride + tungsten(VI) chloride (13283-01-7) → tungsten diboride (12228-69-2)

Guidance literature:

at 850 ℃; for 5h; under 0.00750075 Torr; Sealed tube;

DOI:10.1039/d0cc06072k

Reference yield:

boron + titanium (7440-32-6) + tungsten (7440-33-7) → tungsten diboride (12228-69-2) + (Ti,W)B2

Guidance literature:

In neat (no solvent); byproducts: B2O3; induction-field-activated combustion synthesis; Ti, W and B dry mixed for 1 h (molar ratio to obtain 60 mol% WB2); max. combustion temp. 1800°C, 120 s; cooled slowly; detd. by X-ray powder diffraction;
