Abstract (en)

[origin: WO2006067088A1] The invention relates to a ferrite material with a garnet structure based on yttrium and iron and comprising copper enabling the sintering time thereof to be reduced substantially in comparison with conventional ferrite garnet-type materials, corresponding to the following chemical formula: Y<SUB>a</SUB>TR<SUB>b</SUB>Fe<SUB>c</SUB>Al<SUB>d</SUB>ln<SUB>e</SUB>Ca<SUB>f</SUB>Cu<SUB>g</SUB>Zr<SUB>h</SUB>V<SUB>i</SUB>Co<SUB>j</SUB>Si<SUB>k</SUB>O<SUB>12±y</SUB> wherein TR = a rare earth or combination of rare earths and 3 (a+b+c+d+e) + 2 (f+g+j) + 4 (h+k) + 5i = 24 ± 2y 1=a=3,5; 0=b=1.5; 4=c=5; 0=d=1,5; 0=e<0.8; 0=f=1; 0=g=0,05; 0=i<0.8; 0=j=0.5; 0=k=0.5. Applications: hyperfrequency components, passive inductive low-loss components operating at Gigahertz frequencies.
