Concentrates. Marketable ore concentrates of scheelite and wolframite (hübnerite, ferberite) contain typically 65 – 70 % WO 3.Off-grade concentrates having lower WO 3 concentrations are seldom on the market and if so, only for a lower price. In fully integrated companies lower grades (6-40% WO 3) are often preferred, because …

The infrared and Raman spectra of powder samples of WO 3 (monoclinic and hexagonal) and of WO 3, x H 2 O (x = 1,2, 1 3) have been recorded and the most characteristic vibrations are discussed with reference to the available structural data. In particular, a correlation has been established between the force constant and the length of the W O bond.

Tungsten oxide nanoparticle ink is a hole-selective interface layer ink based on a colloidal suspension of tungsten oxide (WO 3) nanoparticles in isopropanol. The average size of WO 3 particle is optimized around 12-16 nm.

After degassing, the intrinsic structural properties of W03,aHzO are reflected by TUNGSTEN TRIOXIDES 245 the presence of a band at about 950 cm"' in the infrared and Raman spectra (Fig. 7). It can be assigned to W==0 terminal groups but its position would suggest a slightly shorter length than the value of 1.8 A (9).
