Features of Zirconium powder:
 
Zirconium is a chemical element with symbol Zr and atomic number 40. The name of zirconium is taken from the name of the mineral zircon, the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium. Zirconium is mainly used as a refractory and opacifier, although it is used in small amounts as an alloying agent for its strong resistance to corrosion. Zirconium forms a variety of inorganic and organometallic compounds such as zirconium dioxide and zirconocene dichloride, respectively. Five isotopes occur naturally, three of which are stable. Zirconium compounds have no known biological role.

Applications of Zirconium powder:
 
Abrasives, Aerospace, Alloys ,Medical,Nuclear 
1) Because of zirconium's excellent resistance to corrosion, it is often used as an alloying agent in materials that are exposed to corrosive agents, such as surgical appliances, explosive primers, vacuum tube getters and filaments.
2) 90% of all zirconium produced is used in nuclear reactors because of its low neutron-capture cross-section and resistance to corrosion. Zirconium alloys are used in space vehicle parts for their resistance to heat, an important quality given the extreme heat associated with atmospheric reentry.
3) Zirconium is also a component in some abrasives, such as grinding wheels and sandpaper.
4) Zirconium is used in weapons such as the BLU-97/B Combined Effects Bomb for incendiary effect.
5) Zirconium in the oxidized form is also used in dentistry for crowning of the teeth because of its biocompatibility, strength and appearance.
6) High temperature parts such as combustors, blades and vanes in modern jet engines and stationary gas turbines are to an ever increasing extent being protected by thin ceramic layers which reduce the metal temperatures below and keep them from undergoing (too) extensive deformation which could possibly result in early failure. They are absolutely necessary for the most modern gas turbines which are driven to ever higher firing temperatures to produce more electricity at less CO2. These ceramic layers are usually composed by a mixture of zirconium and yttrium oxide.

Iron Boride powder FeB cas 12006-84-7

Specifications of Iron Boride FeB powder
 
Product Name: Iron Boride
CAS number: 12006-84-7
EINECS Number: 234-489-9
Molecular Formula: FeB
Molecular Weight: 215-540-4
 
 
Iron borides have properties of ceramics such as high hardness, and properties of metal properties, such as thermal conductivity and electrical conductivity. Boride coatings on iron are superior mechanical, frictional, and anti-corrosive.
Iron monoboride (FeB) is a gray powder that is insoluble in water. FeB is harder than Fe2B but is more brittle and more easily fractured upon impact. Iron monoboride is only made in single layer.
Iron boride (Fe2B) is a submicron and nanopowder that is also insoluble in water. They have been found to be superconductive and ultra-incompressible. It can be made in both single or double layer.
 
Applications of Iron Boride FeB powder
 
Boriding is often used to improve abrasion resistance, corrosion resistance, wear resistance, and oxidation resistance. It is used in oil and gas refinery, chemical extraction, automotive, agricultural, stamping, textile extrusion and injection molding industries.
Iron based coatings recently gained attention for their mechanical, frictional, and corrosion resistant properties. As compared to the ceramic or cermet type of materials people have used before, iron based materials are relatively inexpensive, less strategic, and can be produced economically by various thermal methods with ease of fabrication and machining.

Product performance

Aluminum boride  is an ionic compound, with hexagonal crystal structure.  Aluminum boride at absolute temperature slightly 40K (equivalent to -233 ¡æ) will be transformed into a superconductor. And its actual operating temperature is 20 ~ 30K. To reach this temperature, we can use liquid neon, liquid hydrogen or closed-cycle refrigerator to finish cooling. Compared to current industry using liquid helium to cool the niobium alloy (4K), these methods are more simple and economical. Once it is doped with carbon or other impurities, magnesium diboride in a magnetic field, or there is a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better.

Applications
superconducting magnets, power transmission lines and sensitive magnetic field detectors.

 

Storage conditions

Aluminum boride nanopowder 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.
