Testing Calcia-Based Refractories for Resistance to Nonferrous Molten Metals

Testing Calcia-Based Refractories for Resistance to Nonferrous Molten Metals Refractory crucibles made of calcium oxide are tested for resistance to molten copper, nickel, cobalt, and slag. A refractory based on CaO and a ceramic bond does not enter into chemical reaction with molten copper, nickel, and cobalt; however, it does react with impurities contained in it such as oxides of copper, nickel, and cobalt. Calcium oxide is shown to exert a refining effect on the molten metals. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Refractories and Industrial Ceramics Springer Journals

Abstract

Refractory crucibles made of calcium oxide are tested for resistance to molten copper, nickel, cobalt, and slag. A refractory based on CaO and a ceramic bond does not enter into chemical reaction with molten copper, nickel, and cobalt; however, it does react with impurities contained in it such as oxides of copper, nickel, and cobalt. Calcium oxide is shown to exert a refining effect on the molten metals.
