Simple introduction for purifying copper nuggets

• Sputtering is one of the main techniques of physical vapor deposition. It is one of the main techniques for preparing electronic thin film materials. It uses ions generated by ion source to accelerate the aggregation in high vacuum and form a high kinetic energy ion beam to bombard the solid surface , Ions and solid surface atoms kinetic energy exchange, the solid surface of the atoms away from the solid and deposited on the surface of the substrate, the bombardment of the solid is sputtering method of deposition of thin film of raw materials, known as sputtering target.

• Copper (Cu) nuggets have been widely used as electrodes and interconnection wires in integrated electronic circuits, and more recently as substrates for the synthesis of graphene. However, the ultra-high vacuum processes required for high-quality Cu film fabrication, such as molecular beam epitaxy (MBE), restricts mass production with low cost. In this work, we demonstrated high-quality Cu thin films using a single-crystal Cu target and radio-frequency (RF) sputtering technique; the resulting film quality was comparable to that produced using MBE, even under unfavorable conditions for pure Cu film growth. The Cu thin film was epitaxially grown on an Al₂O₃(sapphire) (0001) substrate, and had high crystalline orientation along the (111) direction. Despite the 10⁻³ Pa vacuum conditions, the resulting thin film was oxygen free due to the high chemical stability of the sputtered specimen from a single-crystal target; moreover, the deposited film had >5× higher adhesion force than that produced using a polycrystalline target. This fabrication method enabled Cu films to be obtained using a simple, manufacturing-friendly process on a large-area substrate, making our findings relevant for industrial applications.

High purity copper nuggets properties :

• Commercial,high-purity copper nuggets are sent through an electroforming process to further reduce background radioactivity.These nuggets are used in research like the search for dark matter.

For the order:

We are able to offer custom copper rod ,copper particle and cathode copper plate  - please tell us your requirements.  In most cases this will be subject to a minimum ordering quantity and in some cases will be offered on a "best effort" basis.

For the continuous:

If you require material in continuous lengths please tell us when you place your order.  Unless otherwise specified, we reserve the right to supply in more than one length

For the purity of high purity copper nuggets

For materials described in the catalogue as High Purity, the actual analysis of metallic impurities will be supplied free of charge.  For other items, an actual analysis can be supplied and a charge will be made for the analysis and for the sample used.

If you require an analysis, please tell us whether you require analysis of metallic impurities only or metallic and gaseous.  Where an analysis is required the shipment of your order may be delayed.

For the tolerances:

For details of our standard tolerances, please refer to the Product Description section.  In many cases, closer tolerances are available but may be subject to an extra charge.  If you have any special requirements it is important that you tell us at the time of ordering.
