The possibility of using TsTS-19 ceramics in a pyroelectric X-ray source is being experimentally investigated. Measurements of X-ray radiation spectra showed the possibility of obtaining a potential on the ceramic surface up to 7 kV under vacuum conditions, which is an insignificant value in comparison with typical analogous values ??for pyroelectric crystals of lithium niobate and tantalate. This feature is due to the significant value of the dielectric constant of the used ceramics. It is shown that the main criterion for the selection of ceramics for a pyroelectric X-ray source can be the maximum value of the ratio of the pyroelectric coefficient to the dielectric constant
