| 简介 |
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 : YaTRbFecAldlneCafCugZrhViCojSikO12±y 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. |
