Chromium tetraboride (CrB₄), a recently proposed candidate for superhard materials, has been synthesized at high pressure and temperature by a solid-state reaction. As a byproduct, chromium diboride (CrB₂) also forms and co-exists with CrB₄ in the final product. The comparative studies of crystal st...
