More Information
Summary:The subject of the invention is it comprises a compact microstructure containing a multicomponent high refractory chrome-free spinel phase synthesized by arc plasma melting, the composition of which spinel phase is given by the formula Mg0.5Fe0.25Cu0.25Al4.0O4, containing 0.5 molar parts of Mg, 0.25 molar parts of Fe, 0.25 molar parts of Cu and 4.0 molar parts of Al, and it is monophasic material containing a complex multicomponent chrome-free spinel phase from the Mg-Cu-Fe-Al-O system having a pycnometric density ranging from 3.9643 to 4.0580 g/cm3, and present invention also comprises a method of producing this refractory chrome-free spinel material.
