Zirconium oxide thin films were prepared through reactive magnetron sputtering with a zirconium target using pulsed-dc and radio frequency 共 rf 兲 sources. …
Zirconium Oxide Sputtering Targets - Materion
Zirconium oxide is well established as technical ceramic material, due to its superior mechanical and thermal stability. In large-area coating of architectural glass it has recently gained increasing interest. Desirable properties of ZrO2 coatings reported so far include the improved thermal stability of the layer stack, UV blocking properties which can be tuned by nitrogen admixture, as well as a superior scratch resistance [1-4].
Reactive coaxial electrospinning of ZrP/ZrO2 …
Zirconium phosphate/zirconium oxide nanofibres have been fabricated using a novel, reactive coaxial electrospinning approach. In this approach, a zirconium precursor and a phosphorus source are spun together from separate solutions, using a coaxial needle, …
Zirconium Hydroxide as a Reactive Substrate for …
Zirconium hydroxide [Zr (OH) 4 ], with a surface area of 365 m 2 /g, was evaluated for its ability to remove SO 2 from streams of air at room temperature.
WebElements Periodic Table » Zirconium » …
Reaction of zirconium with air. Zirconium metal is coated with an oxide layer that usually renders it inactive. However zirconium does burn in air if provoked to form thedioxide zirconium(IV) oxide, ZrO 2. Zr(s) + O 2 (g) → ZrO 2 (s) Reaction of zirconium with water. Zirconium does not react with water under normal conditions.

dexed as zirconium oxide orthorhombic-type structure (JCPDS card no. 83-0810). The increase of the nitro-gen reactive gas ow rates is followed by the appearance of two clearly distinguished di raction peaks (around 2 of 30:3 and 35:2 ), which may be assigned to the (122) and (214) of a zirconium oxide nitride (JCPDS card no. 48-1637). Up on increasing the to 0.98, an amorphous
Investigation of Various Properties for Zirconium …
01.01.2016 · The increase in argon partial pressure leads to increase in intensity of (111) peak for zirconium oxide thin films as observed by X-ray Diffraction. The average crystallite size of zirconium oxide films increases from 19 nm to 25 nm with increase in argon partial pressure.
Zirconium Alloys - an overview | ScienceDirect …
1.1 Reactor Components Made of Zirconium Alloys and Functions Zirconium alloys have been chosen as fuel cladding and structural components for light and heavy water nuclear reactor cores mainly because of their low capture cross section to thermal neutrons and their good corrosion resistance.

Characterisation of nanostructured ZrO2 thin …
DC reactive magnetron sputtering technique was employed for deposition of zirconium oxide thin films. ZrO 2 films were deposited on to silicon and quartz substrates held at room temperature by sputtering of metallic zirconium target in an oxygen partial pressure of 3x10 -4 Torr and sputter pressure of 3x10 …
Film Properties of Zirconium Oxide Top Layers …
Zirconium oxide thin films were deposited by dual magnetron AC sputtering from rotary cathodes, using both metallic zirconium and novel ceramic zirconium oxide targets. It was found that the ceramic targets can alleviate the severe hysteresis behavior and allows three times higher film deposition rates over the poisoned metal case.
Zirconium - Wikipedia
Zirconium is a lustrous, greyish-white, soft, ductile, malleable metal that is solid at room temperature, though it is hard and brittle at lesser purities. In powder form, zirconium is highly flammable, but the solid form is much less prone to ignition. Zirconium is highly resistant to corrosion by alkalis, acids, salt water and other agents.
Structural and optical properties of thin zirconium …
Thin films of zirconium oxide have been deposited onto glass and Si (100) substrates at room temperature by reactive dc magnetron sputtering of a metallic Zr target in an argon–oxygen atmosphere.
Characterization of ferroelectric …
The room temperature deposition of 10 nm-thick ferroelectric hafnium/zirconium oxide, (Hf, Zr) O 2, thin solid films is achieved with a single hafnium/zirconium, Hf/Zr, alloy target by reactive magnetron sputtering. After rapid thermal annealing (RTA), crystallization of our samples is analyzed by grazing incidence x-ray diffraction.
