IC is useful for the determination of Cr(VI), and possible interferences include iron, copper, nickel, vanadium. Ten µM of any of these interference causes an absorbance of equivalent to approximately 0.02 µM Cr(VI) due to the formation of colored complexes. However, interference due to...

Spectrophotometric Method for the Determination of Atmospheric Cr Pollution as a Factor to Accelerated Corrosion Chromium compounds are used for different anticorrosive layers in water supply and multi-solute reactions in Fig. The main microelements and phosphorus content of sediments formed in a drinking...
Chromium is difficult to work in the pure metal form; it is brittle at low temperatures, and its high melting point makes it difficult to cast. The use of chromium in stainless steel (18%+) is a major use of the element. The U.S. National Occupational Exposure Survey estimated that a...
Chromium has a melting point of 1907 °C (3465 °F), which is relatively low compared to the majority of transition metals. However, it still has the second highest melting point out of all the Period 4 elements, being topped by vanadium by 3 °C (5 °F) at 1910 °C (3470 °F)...
Further, the determination if a product is a single crystal was carried out by an X-ray back reflection Laue method. EXAMPLE 1 High purity chromium obtained by electrolytic refining was sintered by an HIP method. The chromium used contained 99.98% of chromium, 40 ppm of Si, and 50 ppm of...
