Hafnium Metal Industrial Grade 99.9%

Hafnium metal is a kind of transition metal of silver gray metallic, which is in powder, rod, ingot, bar, target and piece. It exists accompany with zirconium normally. There are two crystal structures of hafnium, one is hexagonal close packing (α-type at less than 1300℃, the other is body-centered cubic (β-type). Hafnium rod is ductile metal, however it turn hard and brittle when impurities exist. It is stable in air and turn dark when igniting. Hafnium wire can ignite by match. Its property is close to zirconium. It is soluble in  aqua regia and hydrofluoric acid, but doesn’t dissolve in water, dilute acid or alkali. Hafnium alloy (Ta4HfC5) is the material of highest melting point that is about 4215℃ at present.

Hafnium Metal

CAS No.:7440-58-6 EINECS No.: 231-166-4 Molecular Formula:Hf Molecular Weight:178.49
Melting Point:2227℃ Boiling Point:4602℃ Density:13.3 UN 1326 4.1/PG 2

Applications

Hafnium metal powder can be as cathode of X-ray tube. Hafnium alloys with tungsten or molybdenum can be as electrode of high voltage discharge tube. Hf-Ta alloy is raw material for chisel tool steel and resistance material.

Hafnium powder can be thruster of rocket. it is a kind of additive for hydraulic oil, which prevent the volatilization when high-risk operations. It has strong resistance to volatile. It works in industrial hydraulic oil and medical hydraulic oil.

zirconium powder Industrial Grade 99%

Zirconium metal is available in form of powders, chunks, ingots, lumps, pieces, sheets, foils, particles, slugs, cylinders and targets. It is light gray metal or gray amorphous powder, which is insoluble in water, but soluble in hot concentrated acid, hydrofluoric acid, aqua regia and concentrated sulfuric acid. Zirconium powder would ignite in air when high temperature and turns out zirconium dioxide. The purity of zirconium powder is 99%. The purity of sponge zirconium metal is 99.4%. However the purity of zirconium lump reach 99.9%.

Zirconium Metal

CAS No.: 7440-67-7 EINECS No.: 231-176-9 Molecular Formula: Zr Molecular Weight: 91.224
Melting Point: 1852℃ Boiling Point: 3577℃ Ignition Temperature: >200℃ Density: 6.51

Applications

Zirconium metal powder is for preparation of nuclear industry, corrosion resistance alloy, flashlight and fireworks. It also apply to deoxidizing agent for metallurgy and chemical reagents.

The standard size of zirconium slugs are 1.2*3.5mm, 2*3mm and 1.5mm*3mm. The standard thick of zirconium foils are 0.2mm and 0.3mm. The other sizes could be customizable. Both two products are for vacuum coating, which are sputtering targets.
