Enhancing the sinterability of Ba(Mg1/3Ta2/3)O3 dielectrics by using chemically-derived powders

Smart soft-mechanochemical syntheses of well-crystallized pure phase fine particulates of mixed oxides for electroceramics

“…11,12 A number of synthetic methods were explored. [13][14][15] For the synthesis of BBT, BaCO 3 , in this work, Bi 2 O 3 and Ta 2 O 5 were selected as starting materials. The stoichiometric mixture was milled with nylon balls in vibratory mill for 3 h and was calcined for 1 h in air at temperatures between 850 and 1000 • C. A sample without milling was also prepared for comparison.…”

Low-temperature sintered Zn2SiO4–CaTiO3 ceramics with near-zero temperature coefficient of resonant frequency

“…There are three methods to reduce the sintering temperature of microwave dielectric ceramics: first, low melting oxide, mixture oxide or glass addition; second, chemical processing; and finally the use of smaller particles as the starting materials [11][12][13][14][15][16][17][18][19][20][21]. The chemical method is time-consuming and expensive.…”

Effect of sintering aid on microwave dielectric properties of Mg(Zr0.05Ti0.95)O3 ceramics

“…However, despite its excellent microwave dielectric properties, the disadvantage of the MZrT material is that it requires a high sintering temperature (1420 • C). There are three approaches to reducing the sintering temperature of microwave dielectric ceramics: low melting glass addition [4][5][6], chemical processing [7], and the use of smaller particles as the starting materials [8]. Of these three, glass addition is the most effective and least expensive.…”
