Description of key information
Laser diffraction data for copper oxide show the following ranges of volume-rated particle size distributions: D(v,0.1) 2.68 - 24.03 µm; D(v,0.5) 18.73 - 89.6 µm; D(v,0.9) 46.83 - 899.3 µm. The ranges of number-rated particle size distributions is as follows: D(n,0.1) 0.157 - 0.684 µm; D(n,0.5) 0.220 - 0.943 µm; D(n,0.9) 0.457 - 2.23 µm. None of the grades would fall under the category of nanomaterial (50% < 0.1 µm, based on particle number).
Additional information
Three grades of copper oxide with the following volume-rated and number-rated particle size distributions:
Regular Grade Copper Oxide
Volume-rated distribution: D(v,0.1) 24.03 µm; D(v,0.5) 89.6 µm; D(v,0.9) 899.3 µm.
Number-rated distribution: D(n,0.1) 0.684 µm; D(n,0.5) 0.943 µm; D(n,0.1) 2.23 µm.
Milled Grade Copper Oxide
Volume-rated distribution: D(v,0.1) 8.55 µm; D(v,0.5) 39.0 µm; D(v,0.9) 350.2 µm.
Number-rated distribution: D(n,0.1) 0.277 µm; D(n,0.5) 0.381 µm; D(n,0.1) 0.767µm.
Fine Grade Copper Oxide
Volume-rated distribution: D(v,0.1) 2.68 µm; D(v,0.5) 18.73 µm; D(v,0.9) 46.83 µm.
Number-rated distribution: D(n,0.1) 0.157 µm; D(n,0.5) 0.220 µm; D(n,0.1) 0.457 µm.
Based on the results from the number distributions, none of the tested grades would fall under the category of nanomaterial (50% < 0.1 µm, based on particle number).
Ranges for the volume-based distributions across all grades were as follows: D(v,0.1) 2.68 - 24.03 µm; D(v,0.5) 18.73 - 89.6 µm; D(v,0.9) 46.83 - 899.3 µm.
Ranges for the number-based distributions across all grades were as follows: D(n,0.1) 0.157 - 0.684 µm; D(n,0.5) 0.220 - 0.943 µm; D(n,0.9) 0.457 - 2.23 µm.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
