Description

Исходные сырьевые материалы в виде оксидов (барий вводитс  в виде BaZrOs).The raw materials are in the form of oxides (barium is introduced in the form of BaZrOs).

После смешивани  в вибромельнице и сепарировани  прессуют в брикеты и подвергают предварительному обжигу при 950°С. Брикеты измельчают в вибромельнице, сепарируют , прессуют заготовки и обжигают в туннельной печи при 1200°С в течение 1 ч.After mixing in a vibromill and separation, it is pressed into briquettes and pre-baked at 950 ° C. The briquettes are ground in a vibrating mill, separated, pressed into blanks, and burned in a tunnel kiln at 1200 ° C for 1 hour.

Диэлектрические и пьезоэлектрические характеристики материала определ ют на издели х диаметром 12 мм толщиной 2 мм.The dielectric and piezoelectric characteristics of the material are determined on products with a diameter of 12 mm and a thickness of 2 mm.

Испытани  материала показывают, что он имеет более высокие значени  параметров: Яз1 10,2-10-3 в/м, 31 300-10-12 ,Material tests show that it has higher parameter values: Yaz1 10.2-10-3 w / m, 31 300-10-12,
