NdBCO 1-2-3 (SS 99.99%) Powders

Scope:

This product data sheet characterizes Neodymium Barium Copper Oxide (NdBCO123) SS-99.99% superconducting powders produced by SCI Engineered Materials™ (SCI). The following information is not a specification; however, it may prove useful to the customer in developing a formal product specification.

General Description:

SCI offers NdBa2Cu3Ox powders manufactured by a solid state method. A mixture of fine powders of oxides and carbonates of metallic elements are mixed and suspended in a slurry for effective milling. Appropriate grinding media and containers are used to minimize any contamination.

The starting raw materials (Nd2O3, BaCO3 and CuO) with 99.99% purity are used. Phase pure, low carbon content superconducting powders are obtained by using a low pressure calcination method. The low processing temperatures employed in this method results in powders with fine particle size. Powders with customized stochiometry and dopings are also available on request.

Thermal analysis and x-ray diffraction and its typical microstructure are shown below.

Typical Impurities (starting powder, in ppm):

Handling Instructions:

Handling precautions are given in MSDS sheet enclosed.
