The particle sizes of micronized copper formulations derived from treating liquids were compared with those deposited in wood treated with those liquids. The intent was to determine if agglomeration occurs in the liquids during the treatment process, if screening of the agglomerates occurs in the wood and if there are any apparent differences in the particle sizes in the wood. Three formulations were prepared using micronized copper that had significantly different particle sizes and then five replicate blocks were treated with the formulations. Scanning electron microscopy was used to measure and compare the particle sizes. Only the formulation with very small particle sizes (mean <100 nm) showed any differences between the liquid and the wood.
