The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, tungsten which means heavy stone.

Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds rather than alone.

Its important ores include wolframite and scheelite. The free element is remarkable for its robustness, especially the fact that it has the highest melting point of all the elements discovered, melting at 3,422 °C.

It also has the highest boiling point, at 5,930 °C. Its density is times that of water, comparable with that of uranium and gold, and much higher than that of lead.

Polycrystalline tungsten is an intrinsically brittle and hard material (under standard conditions, when uncombined), making it difficult to work.

However, pure single-crystalline tungsten is more ductile and can be cut with a hard-steel hacksaw. Tungsten's many alloys have numerous applications, including incandescent light bulb filaments, X-ray tubes as both the filament and target), electrodes in gas tungsten arc welding, superalloys, and radiation shielding.

Tungsten's hardness and high density give it military applications in penetrating projectiles. Tungsten compounds are also often used as industrial catalysts.

Tungsten is the only metal from the third transition series that is known to occur in biomolecules that are found in a few species of bacteria and archaea. It is the heaviest element known to be essential to any living organism.

However, tungsten interferes with molybdenum and copper metabolism and is somewhat toxic to more familiar forms of animal life.

Ultrafine Tin Particle Powder

Product Name: Ultrafine Tin Particle Powder

Application of Ultrafine Tin Particle Powder:

1. Metal nano-lubricating additive: Adding 0.1~1% nano-tin powder to lubricating oil and grease, the self-lubricating and the self-repairing film is formed on the surface of the friction pair during friction, which significantly reduces the anti-wear and anti-friction performance of the friction pair.
2. Activated Sintering Additive: Nano-tin powder greatly reduces the sintering temperature of powder metallurgical products and high-temperature ceramic products in powder metallurgy.
3. Metallic and non-metallic surface conductive coating treatment: The coating is applied under anaerobic conditions at a temperature below the melting point of the powder. This technique can be used for the production of microelectronic devices.

Product Name: Vanadium Oxide Powder

Vanadium Oxide Powder Description  :

Vanadium oxide Powder (vanadia) is the inorganic compound with the formula V2O5. Commonly known as vanadium pentoxide,

It is a yellow solid, although when freshly precipitated from aqueous solution, its color is deep orange. Because of its high oxidation state, is both an amphoteric oxide and an oxidizing agent. From the industrial perspective,

It is the most important compound of vanadium, being the principal precursor to alloys of vanadium and is a widely used industrial catalyst. It is also used as a catalyst in the selective catalytic reduction (SCR) of NOx emissions in some power plants.

Due to its effectiveness in converting sulfur dioxide into sulfur trioxide, and thereby sulfuric acid, special care must be taken with the operating temperatures and placement of a power plant's SCR unit when firing sulfur-containing fuels.

Product Name: Ytterbium Oxalate Decahydrate Powder

Ytterbium Oxalate Decahydrate Description :

Ytterbium is a chemical element with the symbol Yb and atomic number 70. It is the fourteenth and penultimate element in the lanthanide series, which is the basis of the relative stability of its  oxidation state.

However, like the other lanthanides, its most common oxidation state is, as in its oxide, halides, and other compounds. In aqueous solution, like compounds of other late lanthanides, soluble ytterbium compounds form complexes with nine water molecules.

Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. Natural ytterbium is a mixture of seven stable isotopes, which altogether are present at concentrations of 3 parts per million.

The ytterbium concentration is low because it is found only among many other rare earth elements; moreover, it is among the least abundant. Once extracted and prepared, ytterbium is somewhat hazardous as an eye and skin irritant. The metal is a fire and explosion hazard.

Product Name: Yttrium Fluoride Powder

 Yttrium Fluoride Description

Yttrium Fluoride of yttrium are yttrium oxide and yttrium hydroxide, respectively, and they are both white solids which are hardly soluble in water. Among them, yttrium oxide can be prepared by heating yttrium carbonate or yttrium oxalate. Alternatively, the oxychloride can be heated in air to yield the oxide.

Yttrium Fluoride can be precipitated by the reaction of soluble yttrium compounds with sodium hydroxide or ammonia, and can also be obtained by the hydrolysis of yttrium alkoxide. Hydroxy acids and sugars present in the solution will prevent the formation of precipitates due to the formation of stable coordination compounds.

Yttrium Fluoride can be decomposed by heating. Firstly, basic yttrium oxide is formed, and when heating is continued yttrium oxide is obtained. Both yttrium oxide and Yttrium Fluoride are easily soluble in strong acids to form corresponding yttrium salts.

Zinc Sulphide Powder

Product Name: Zinc Sulphide Powder

Zinc Sulphide Powder Description

Zinc sulfide Powder is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment. In its dense synthetic form, zinc sulfide can be transparent, and it is used as a window for visible optics and infrared optics.

Both sphalerite and wurtzite are intrinsic, wide-bandgap semiconductors. These are prototypical semiconductors, and they adopt structures related to many of the other semiconductors, such as gallium arsenide. The cubic form of ZnS has a bandgap of about electron volts at 300 kelvins, but the hexagonal form has a bandgap of about electron volts.

ZnS can be doped as either an n-type semiconductor or a p-type semiconductor. Fine ZnS powder is an efficient photocatalyst, which produces hydrogen gas from water upon illumination. Sulfur vacancies can be introduced in ZnS during its synthesis; this gradually turns the white-yellowish ZnS into a brown powder, and boosts the photocatalytic activity through enhanced light absorption Zinc sulfidic, with the addition of few ppm of suitable activator, exhibits strong phosphorescence, and is currently used in many applications, from cathode ray tubes through X-ray screens to glow in the dark products. When silver is used as an activator, the resulting color is bright blue, with a maximum at 450 nanometres.

Using manganese yields an orange-red color at around 590 nanometres. Copper gives a long-time glow, and it has the familiar greenish glow-in-the-dark. Copper-doped zinc sulfidic is used also in electroluminescent panels. It also exhibits phosphorescence due to impurities on illumination with blue or ultraviolet light.
