Dark blue nano tungsten oxide is a kind of semiconductor material with good chemical stability that may be applied in manufacturing semiconductor devices and electronic material of integrated circuits. There are studies on preparing a kind of tungsten oxide semiconductor battery, which has semiconductor chemical, photoelectric and thermoelectric and other properties. It is to say this kind of battery can produce electronic transport between two electrodes, and the battery current will increased significantly under the sun. Furthermore, the current increases…

Blue tungsten oxide nanopowder may be applied in the electronics industry. Electronics is the science of controlling electrical energy electrically and deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies. With the advent of flexible electronics, people have realized that the future electronic products have a significant breakthrough in the field of human-computer interaction, such as nowadays the more and more popular wearable electronic products,…

Blue nano tungsten oxide’s price affecting factors are mainly listed as follows: 1. The large production capacity of tungsten raw materials (tungsten concentrate, APT) cause an imbalance between supply and demand, directly affecting the price of blue tungsten oxide. 2. Tungsten mine cost and the nature of tungsten mine enterprise directly affect price. State-owned enterprises control a large number of BTO products and form price protection. 3. The production of tungsten concentrate is relatively concentrated, forming a certain price monopoly…

Micro fine blue tungsten oxide’s XPS experiment is using a surface-sensitive quantitative spectroscopic technique to systematically analyze the valence changes of blue tungsten oxide during tungsten powder producing from tungsten ore. XPS is the short for X-ray photoelectron spectroscopy. XPS Experiment of Micro Fine Blue Tungsten Oxide 1. The blue tungsten oxide powder sampled in the producing process is pressed into a φ11mm disc and delivered into ESCALAB-5. The multi-ding photoelectron spectrometer has an ultimate pressure of 2×10-10mbar. 2. An…

TBO is the abbreviation for tungsten blue oxide. It is not a defined tungsten compound, but a powdery mixture of multiple tungsten compounds whose chemical composition and physical properties are changing. Tungsten blue oxide is gradually replacing traditional tungstic acid and yellow tungsten oxide (tungsten trioxide) to become an important tungsten intermediate compound. TBO is generally composed of ammonium tungsten bronze, hydrogen tungsten bronze, tungsten trioxide (WO3, yellow tungsten oxide), β-tungsten oxide (WO2.9, blue tungsten oxide) and γ-tungsten oxide (WO2.72,…

BTO nanopowder has good catalytic performance and is the main catalyst or auxiliary catalyst in the petrochemical industry. It can also catalyze many reactions such as hydrogenation, dehydrogenation, oxidation, hydrocarbon isomerization, alkylation, and so on. Hydrogenation and dehydrogenation are two different reactions. Hydrogenation is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. However, dehydrogenation refers to the chemical reaction which removes hydrogen from…

Ultrafine BTO powder may be prepared by APT calcination method. APT Calcination Method to Produce Blue Tungsten Oxide The principle is during heating process, keep positive pressure in furnace to prevent air goes in, and the ammonia generated by APT decomposition can split out hydrogen and nitrogen to keep the mild reducing atmosphere in furnace to obtain the final product – blue tungsten oxide. Besides that, in order to adjust phase composition of product, ammonia gas can be injected in…

Coarse BTO powder may be prepared by APT mild hydrogen reduction method. APT Mild Hydrogen Reduction Method to Produce Blue Tungsten Oxide After loaded on a boat, APT is placed in a multi tube furnace (11 tube electric furnace) and decomposed by heating. Hydrogen is injected into the furnace tube to maintain the reducing atmosphere. The decomposed gas and waste gas are ignited and burned out of the furnace tube. Phase composition of blue tungsten oxide can be adjusted by…
