Influence of Synthesis Conditions on Tungsten Oxide Functional Properties

Details: Category: Tungsten Information; Published on Thursday, 05 February 2015 10:51; Written by cq; Hits: 1532

Knowledge of the relation between the synthesis conditions of specific metal oxide and its functional properties is important for the possible application of metal oxides in advanced technologies. The chemical and physical properties of tungsten oxide are generally dependent on the route of their synthesis.

Tungsten oxide and its hydrates can be synthesized using various chemical methods, such as ‘wet’ chemical precipitation, hydrolysis of tungsten alkoxide or thermal decomposition of tungsten salts. The WO3 films on various substrates can also be prepared using various vacuum techniques. Modification of the chemical or physical route within the same method also influences the resulting properties of the synthesized material.

Where Is Tungsten Oxide From?

Details: Category: Tungsten Information; Published on Thursday, 05 February 2015 10:43; Written by cq; Hits: 1489

Tungsten oxide is obtained from the minerals scheelite, wolframite, ferberite. It is insoluble in H2O and acids, but soluble in hot alkalis.

Intermediates, such as tungsten trioxide, tungsten blue oxide, tungstic acid, and ammonium metatungstate can be derived from APT, either by partial or complete thermal decomposition or by chemical attack.

Stoichiometric compounds such as W20O58, W18O49 or WO2 are formed intermediately during the reduction process and can be isolated by interrupting the reduction process at the selected reduction state.

BICC, England Full-County Darts Championship (BICC) for BDO run the entire system is very critical, it is also responsible for training darts players, these players will continue to regularly participate in national, world and professional levels of the game industry. BICC's most famous, are all recognized as darts line, County by forty-three England, 16 in Scotland County and seven Welsh county components, which produces a main area and the District 1,2,3,4 in England and Wales, plus two Scottish areas ,It is from September to April, held every three to four weeks time,

British Darts Organization (THE BRITISH DARTS ORGANISATION) was established in 1973, called BDO. BDO darts in the UK is one of the relevant government organizations, it is to regulate the organization, improvement, operation, management, training darts for the purpose, to make it more national, international, world-oriented.

England and Wales each district has ten counties, each county is divided into male and female players A and B teams, and each team of twelve male and six female athletes. So that each county will have thirty-six players, and on behalf of the county to participate in the competition between the county and the county in every three to four weeks time.

Cricket

Details: Category: Tungsten Information; Published on Wednesday, 04 February 2015 18:20; Written by xsh; Hits: 445

Cricket is a widely-played darts game involving a race to control and score on numbers between 20 and 15 and the bulls eye, by hitting each of these targets for three marks to open or own it for scoring. A hit on the target counts as one mark, while hits in the doubles ring of the target count as two marks in one throw, and on the triples ring as three. Once opened in this manner, until the opponent closes that number with three marks on it of their own, each additional hit by the owner/opener scores points equal to the number of the target (which may also be doubled and tripled, e.g. a triple-20 is worth 60 points). The outer bulls eye counts as 25 points, and the inner as 50.
