High Purity Ntshiab Nickel Granules

High purity ntshiab npib tsib xee granules yog siab -purity metallic khoom uas tuav qhov tseem ceeb nyob rau hauv niaj hnub kev lag luam thiab kev tshawb fawb teb vim lawv zoo heev lub cev, tshuaj, thiab txhua yam khoom.

High purity ntshiab npib tsib xee granules xa mus rau granular cov ntaub ntawv uas feem ntau yog xim hlau npib tsib xee (Ni) uas tsis tshua muaj impurity cov ntsiab lus.

Industrially, nws yog feem ntau cais raws li purity:

1. Muaj-qib npib tsib xee: Ni ntau dua lossis sib npaug li 99.0% (xws li, 99.2%, 99.5%), nrog impurities suav nrog Fe, Cu, S, C, thiab lwm yam, siv rau cov pa electroplating thiab metallurgical alloys;
2. High-purity npib tsib xee (4N): Ni ntau dua lossis sib npaug li 99.99%, haum rau cov txheej txheem hluav taws xob thiab cov khoom siv hluav taws xob;
3. Ultra-siab-purity npib tsib xee (5N): Ni ntau dua lossis sib npaug li 99.999%, nrog cov impurities tswj ntawm ppm / ppb qib, siv hauv semiconductors, aerospace siab- cov ntaub ntawv kawg, thiab precision alloys.

Qhov tshwm sim: Nyiaj -dawb nrog cov xim hlau nplaum. Cov duab muaj xws li spherical, irregular granules, thiab cylindrical hais. Qhov ntau thiab tsawg ntawm kaum micrometers mus rau ntau millimeters (xws li 3 × 3 mm, 6 × 6 mm cylindrical hais; atomized kheej kheej hais feem ntau 15-45 μm).

High purity ntshiab npib tsib xee granules tuaj ntau hom nyob ntawm lawv daim ntawv thov:

• Cubic particles: Yooj yim rau kev khaws cia thiab kev thauj mus los, tsim nyog rau kev ntsuas qhov hnyav thiab me me -batch siv.
• ‌Sphereical/ze-spherical particles: Zoo heev flowability, zoo tagnrho rau automated pub, additive manufacturing, thiab roj teeb electrode txheej.
• Particle loj ntau yam: Feem ntau 1-30 mm, precisely graded ntawm sieving kom tau raws li cov txheej txheem tshwj xeeb.

Muab faib los ntawm qhov ntau thiab tsawg:

1. Cylindrical hais (qhov tseem ceeb rau txheej / smelting)

Φ3 × 3 hli Φ3 × 5 mm

Φ4 × 4mm Φ5 × 5mm

Φ6 × 6 hli

2. Cov khoom tsis zoo

1-3 hli 2-5 mm

3-8 hli 5-15 mm

1. Yam tseem ceeb ntawm lub cev:Atomic hnyav 58.69; Qhov ceev 8.902 g / cm³; Melting point 1453 degree, Boiling point 2732 degree; Lub ntsej muag -centered cubic crystal qauv ntawm chav tsev kub, nthuav tawm ferromagnetism (Curie kub 354 degree); Hluav taws xob tiv taus kwv yees li 6.84 μΩ・cm (20 degree); Thermal conductivity: 90.9 W / (m·K);
2. Chemical Stability:Resistant atmospheric, dej tshiab, thiab qaug zog alkali corrosion ntawm chav tsev kub; maj mam yaj hauv cov uas tsis yog -oxidizing acids; muaj zog oxidizing acids (concentrated nitric acid) tuaj yeem passivate nws; nkag oxidizes rau NiO ntawm qhov kub thiab txias; dissolves nyob rau hauv dilute nitric acid los ua ib tug ntsuab nickel ion tov;
3. Mechanical Properties:Kev lag luam- qib ntshiab npib tsib xee nthuav tawm ib chav- qhov kub thiab txias tawm lub zog Ntau dua lossis sib npaug li 240 MPa, lub zog tensile Ntau dua lossis sib npaug rau 520 MPa, thiab elongation Ntau dua lossis sib npaug li 45%. Nws muaj cov yas zoo heev thiab haum rau kev ua haujlwm txias. High -purity particles, tus yam ntxwv los ntawm cov impurities tsawg thiab cov qauv zoo li qub, ua kom pom kev zoo dua weldability thiab sinterability.

1. Electronics thiab Semiconductors:Evaporation/sputtering txheej hom phiaj cov ntaub ntawv, tuab - zaj duab xis Circuit Court pastes, connector plating; 5N- qib particles rau nti ntim thiab integrated circuits;
2. Catalysis thiab Chemical Engineering:Hydrogenation cov tshuaj tiv thaiv catalysts (piv txwv li, nickel moj khaum / Raney nickel), petrochemical desulfurization catalysts;
3. Cov roj teeb hluav taws xob tshiab:Nickel{0}}hlau hydride roj teeb cathodes, cov ntaub ntawv ua ntej rau lithium-ion ternary cathodes (NCM/NCA);
4. Hmoov Metallurgy & Additive Manufacturing:3D- luam tawm ntshiab npib tsib xee / npib tsib xee-raws li cov khoom siv hlau rau cov khoom siv dav hlau;
5. Electroplating thiab metallurgy:Electroplating anode cov ntaub ntawv, nickel additives rau stainless hlau thiab siab -kub alloys (xws li, Inconel 718);
6. Cov khoom siv hlau nplaum:Kev tsim cov hlau nplaum mos mos thiab cov khoom siv hluav taws xob tiv thaiv hluav taws xob.

• High Corrosion Resistance: Pom muaj zog ruaj khov ntawm chav sov tiv thaiv dej, huab cua, alkaline ib puag ncig, thiab ntau cov kua qaub (xws li dilute sulfuric acid thiab hydrochloric acid). Nws nto tau yooj yim tsim cov yeeb yaj kiab oxide tuab uas tiv thaiv corrosion ntxiv.
• Zoo heev -Tsuas Kub Stability: Nrog lub melting point siab li 1455 degree, nws tswj cov txheej txheem kev ncaj ncees txawm nyob rau hauv siab - kub oxidizing atmospheres, ua rau nws haum rau siab - kub alloy manufacturing.
• Magnetic Properties: Nickel yog ib qho ntawm ob peb ferromagnetic hlau, nrog Curie point ntawm 357.6 degree. Nws pom kev siv dav hauv cov khoom siv hluav taws xob thiab cov khoom sib nqus.
• Kev ua haujlwm siab: Yooj yim ua tiav rau hauv ntau hom- xws li hmoov, nplooj ntawv, lossis granules-los ntawm txoj kev xws li dov, forging, thiab kos duab hlau.
