highimpurity
High impurity refers to a material containing a relatively large amount of undesired foreign elements or compounds relative to its intended composition. In metals, ceramics, polymers, and especially semiconductors, impurities are atoms or molecules that are not the primary constituent. A high impurity level is typically defined by industry purity standards, specification limits, or comparison with a reference high-purity material, and it often accompanies changes in microstructure and properties.
Causes of high impurity include contamination during processing (wear particles, furnace atmospheres, or equipment leaching), impure
Measurement and characterization of impurities rely on analytical techniques such as X-ray fluorescence (XRF), inductively coupled
Impacts of high impurity are broad. They can alter mechanical properties (strength, ductility, hardness), electrical and
Mitigation generally involves purification and refining, improved process controls, cleaner sources, and containment strategies. In some
