Материал получают следующим образом.The material is obtained as follows.
После помола исходных веществ из полученной щихты изготовл ют брикеты. Брикеты подвергают синтезу при 850°С в течение 2 час, затем тщательно измельчают в порощок с размером частиц 3-5 мкм, после чего добавл ют раствор поливинилового спирта в качестве св зки и прессуют издели заданной формы и величины. Спреесованные издели спекают при 1220-1230°С в атмосфере окиси свинца.After grinding the starting materials, briquettes are made from the resultant solid. Briquettes are synthesized at 850 ° C for 2 hours, then thoroughly crushed into powders with a particle size of 3-5 µm, after which a solution of polyvinyl alcohol is added as a binder and pressed into articles of a given shape and size. The packed products are sintered at 1220-1230 ° C in an atmosphere of lead oxide.
После спекани образцы ишифуют. Электроды нанос т вжиганием при 700°С в течение 20 мин.After sintering, the samples are encrypted. Electrodes are applied by firing at 700 ° C for 20 minutes.
Пол ризацию изделий осуществл ют в полисилоксановой жидкости при 100°С в теСостав , вес.лThe polarization of the products is carried out in a polysiloxane fluid at 100 ° C in the composition, weight l
