“Possible substitutes for molybdenum as a strengthening alloy in steel include vanadium, chromium, columbium, and boron.”
“In the presence of columbium the solution first becomes blue and then changes to a turbid brownish-black”
“Thus C stands for carbon, Cl for chlorine, Cd for cadmium, Ce for cerium, Cb for columbium.”
“There are five metals, arsenic, molybdena, chrome, tungsten, and columbium, which are susceptible of combining with a sufficient quantity of oxygen to be converted into acids.”
“The nozzle material is made of columbium and heats up during the test causing the color change.”
“Materials classified as carbon steel might also contain small amounts of other elements, such as chromium, nickel, molybdenum, copper, vanadium, niobium (columbium), phosphorous, and sulfur.”
“His claim was refuted when another English chemist named William Hyde Wollaston claimed Hatchett's columbium was just another form of the element tantalum.”
