Grade 1 violet tungsten oxide nanopowder adopts tungstic acid (mWO3?nH2O, m≥1, n≥1) as raw material. And the VTO may be produced by calcinating and reducing mWO3?nH2O in a hydrogen reducing atmosphere. Hydrogen Reduction Method to Prepare Nano Needle-shaped Violet Tungsten Oxide Step one: By using feeding device, feed tungstic acid from the feed end into the heated furnace tube, and gradually move it from low temperature zone to high temperature zone under the rotation of inclining furnace tube; Step two:…
Super grade violet tungsten oxide nanopowder may be prepared by calcining ammonium paratungstate with formula of 5(NH4)2O?12WO3?5H2O, APT for short. The steps for calcining APT to prepare super grade violet tungsten oxide nanopowder are as follows: Step one: Feed 5(NH4)2O?12WO3?5H2O from the feed inlet into the heated furnace tube with a feeding device, gradually moving from the low temperature zone to high temperature zone under the rotation of inclined furnace tube. Step two: Calcine 5(NH4)2O?12WO3?5H2O to generate WO3, NH3 and…
High-purity violet tungsten oxide nanopowder may be prepared by using tungsten oxide WOx (2≤x≤3) as raw material. Adopt WOx, or WOx generated during preparation as raw material; NH3 and/or H2 are introduced through the air inlet, and water vapor is introduced depending on WOx. If NH3 is introduced, NH3 will react under the catalytic effect of WOx in formula (1) at high temperature: 2NH3=N2+3H2 (1) 1. WOx contains WO3. When the reaction temperature rises above 500°C, WO3 reacts with the…
Crystalline violet tungsten oxide has some difference with crystalline yellow tungsten oxide and crystalline blue tungsten oxide. That is because the oxygen content of these tungsten oxides varies from each other. And it is mainly reflected in appearance, molecular formula, boiling point and other properties. The difference between violet tungsten oxide and yellow tungsten oxide and blue tungsten oxide is shown as below: 1. Violet Tungsten Oxide (1) Also known as γ-tungsten oxide, abbreviated for VTO; (2) Appears violet or…
