WebNov 13, 2024 · Electrical resistivity of Chromium is 125 nΩ·m. Electrical resistivity and its converse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts the flow of electric current. A low resistivity indicates a material that readily allows the flow of electric current. WebApr 9, 2024 · Gel materials such as acrylics, resins, and conductive polymers (CPs) were used to study the feasibility of chromate adsorption. (1) Acrylics can form gels with water as the dispersion medium. It can introduce hydrophobic groups into the water-soluble polymer with the cross-linked structure to form a cross-linked polymer that can expand when ...

Chromate - an overview ScienceDirect Topics
Recent studies have shown that not only is zinc chromate highly toxic, it is also a carcinogen. Exposure to zinc chromate can cause tissue ulceration and cancer. A study published in the British Journal of Industrial Medicine showed a significant correlation between the use of zinc chromate and lead chromate in factories and the number of cases in lung cancer experienced by the workers. Because of its toxicity the use of zinc chromate has greatly diminished in recent ye… WebN. Koleli, A. Demir, in Environmental Materials and Waste, 2016 11.2.3.3 Waste of Chemical Industry.
