Europium Oxide is also applied in speciality plastic for laser material.

One of the platinum group metals, osmium is bluish-white, lustrous, extremely hard and brittle. Its properties make it ideal for combining with other platinum metals to produce very hard alloys. Osmium has the highest melting point and lowest vapor pressure of the platinum group and it is very difficult to fabricate. While osmium powder or sponge is affected by air at room temperature, the metal is relatively inert in ambient conditions.


Osmium (Os) Typical Applications:

• Because of the volatility and extreme toxicity of its oxide, osmium is rarely used in its pure state, and is instead often alloyed with other metals that are used in high-wear applications. Osmium alloys such as osmiridium are very hard and, along with other platinum group metals, is almost entirely used in alloys employed in the tips of fountain pens, instrument pivots, and electrical contacts, as they can resist wear from frequent use. The stylus (needle) in early phonograph designs was also made of osmium, especially for 78-rpm phonograph recordings, until industrial diamond replaced the metal in later designs.
• Osmium tetroxide has been used in fingerprint detection and in staining fatty tissue for microscope slides. As a strong oxidant, it cross-links lipids mainly by reacting with unsaturated carbon-carbon bonds, and thereby both fixes biological membranes in place in tissue samples and simultaneously stains them, since osmium atoms are extremely electron dense, making OsO4 an important stain for transmission electron microscopy (TEM) studies of many biological materials. An alloy of 90% platinum and 10% osmium (90/10) is used in surgical implants such as pacemakers and replacement pulmonary valves.
• The tetroxide (and a related compound, potassium osmate) are important oxidants for chemical synthesis, despite being very poisonous.
• In 1898 an Austrian chemist, Auer von Welsbach, developed the Oslamp with a filament made of osmium, which he introduced commercially in 1902. After only a few years, osmium was replaced by the more stable metal tungsten (originally known as wolfram). Tungsten has the highest melting point of any metal, and using it in light bulbs increases the luminous efficacy and life of incandescent lamps.
• The light bulb manufacturer OSRAM (founded in 1906 when three German companies; Auer-Gesellschaft, AEG and Siemens & Halske combined their lamp production facilities), derived its name from the elements of OSmium and wolfRAM.
• Like palladium, powdered osmium will densely absorb hydrogen atoms, perhaps making it a potential candidate as a metal hydride battery electrode substance, but it will react with potassium hydroxide, the most common battery electrolyte.

We are offering hafnium powder.Found in all minerals containing zirconium, hafnium is a ductile metal with a brilliant silver luster. It is strong and extremely corrosion resistant. Zirconium and hafnium's chemistry are virtually identical (except that hafnium's density is twice that of zirconium) and, therefore, are extremely difficult to separate. Hafnium's properties are significantly influenced by the zirconium impurities present. Higher purities are available. hafnium (hf) metal typical applications: most of the hafnium produced is used in the production of control rod for nuclear reactors.Hafnium containing rocket nozzle of the apollo lunar module in the lower right corner. Hafnium is used in iron, titanium, niobium, tantalum, and other metal alloys. An alloy used for liquid rocket thruster nozzles, for example the main engine of the apollo lunar modules is c103, which consists of 89% niobium, 10% hafnium and 1% titanium.Small additions of hafnium increase the adherence of protective oxide scales on nickel based alloys. It improves thereby the corrosion resistance especially under cyclic temperature conditions that tend to break oxide scales by inducing thermal stresses between the bulk material and the oxide layer.The electronics industry discovered that hafnium-based compound can be employed in gate insulators in the 45 nm generation of integrated circuits from intel, hafnium oxide-based compounds are practical high-k dielectrics, allowing reduction of the gate leakage current which improves performance at such scales.Due to its heat resistance and its affinity to oxygen and nitrogen, hafnium is a good scavenger for oxygen and nitrogen in gas-filled and incandescent lamps. Hafnium is also used as the electrode in plasma cutting because of its ability to shed electrons into air.

Application of price europium rare earth metals:

Europium Metal, is very valuable material in control rods for nuclear reactors due to that it can absorb more neutrons than any other elements. It is a dopant in some types of glass in lasers and other optoelectronic devices. Europium is also used in the manufacture of fluorescent glass. A recent (2015) application of Europium is in quantum memory chips which can reliably store information for days at a time; these could allow sensitive quantum data to be stored to a hard disk-like device and shipped around the country.

Titanium hydride TiH2 is a metal hydride formed from titanium and hydrogen. titanium hydroxide is a active chemical material, need to be kept away from high-temperature and strong oxidants.Because titanium hydride TiH2  is relatively stable in air, titanium hydroxide can also be used to prepare hydrogen and titanium hydroxide. titanium hydroxide can be obtained by reacting hydrogen with titanium metal directly. Above 300 °C, the metal titanium can reversibly absorb hydrogen, and finally forms a compound of the formula TiH2. If heated to above 1000°C, titanium hydride will be fully decomposed into titanium and hydrogen. At a sufficiently high temperature, the hydrogen-titanium alloy is in equilibrium with the hydrogen, at which time the partial pressure of hydrogen is a function of the hydrogen content and temperature in the metal.
Titanium hydride TiH2 Common applications include ceramics, pyrotechnics, sports equipment, as a laboratory reagent, as a blowing agent, and as a precursor to porous titanium. When heated as a mixture with other metals in powder metallurgy, titanium hydride releases hydrogen which serves to remove carbon and oxygen, producing a strong alloy.

 

Uses: titanium powder raw materials, foaming materials, powder metallurgy, hard alloy additive, fireworks. 
Storage conditionsThis product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation.
