METHOD OF FORMING COMPOSITION OF SOLID SOLUTIONS WITH PREDETERMINED PARAMETERS FOR HIGH-FREQUENCY AND MICROWAVE ENGINEERING ARTICLES Russian patent published in 2003 - IPC

FIELD: solid solutions. SUBSTANCE: invention aims at forming following system: (Ba_1-xA_x)Ln₂Ti₄O₁₂, in which element A is selected from Ca, Pb, Ln-Nd, and additionally titanium-replacing element B: Zr is added. If A is selected from Ca, Sr, and Pb, lanthanoid Ln is Nd and/or Sm and additionally titanium-replacing element B: Zr or Hf and lanthanoid- replacing element C: Bi are added. EFFECT: optimized combination of following parameters: dielectric permittivity, quality factor, and temperature resistance. 8 cl, 2 tbl
