Abstract | The existence of eleventh new compounds with the structure type Sc2Re3Si4: Dy2{Zr, Hf}3Si4, Ho2{Zr, Hf}3Si4, Er2{Zr, Hf}3Si4, Tm2{Zr, Hf}3Si4, Lu2{Ti, Zr, Hf}3Si4 is found on the basis of X-ray phase, X-ray structure, and local energy-dispersive X-ray analyses, and the existence of the compounds Tb2Ti3Si4 and Er2Ti3Si4 at 870 K is confirmed. It was determined that the unit cell parameters of isostructural compounds consistently increase with the replacement of titanium atoms by zirconium and decrease with the replacement of zirconium atoms by hafnium. |
Keywords | hafnium, isostructural compounds, titanium, unit cell parameters, zirconium |
