Features of obtaining a vacuum-dense weakly conductive ceramics based on barium aluminate
Ceramics based on barium aluminate with additives of iron (III) oxide and lithium hydroxide were obtained by solid-phase synthesis. It has been established that high-temperature treatment in an oxidizing medium contributes to the production of vacuum-dense samples that meet the «absolutely impermeable» tightness criterion, with a density of 3,75 g/cm3 , with a compressive strength limit of 597,1 MPa and a specific electrical conductivity in the range of 1,50·10‒7‒1,05·10‒4 Cm/ cm (at 90‒300 °C).
