We present a ceramic material based on hematite (Fe$_2$O$_3$) and zirconiastabilized with yttria at 8% molar (YSZ), that exhibits stable electricalproperties with transported charge and that can be tuned to the resistivitiesnecessary to induce spark-quenching in gaseous detectors ($\rho = 10^9-10^{12}$$\Omega \cdot$cm), from room temperature down to the liquid-vapor coexistencepoint of nitrogen (77 K). It, thus, allows covering the operating temperaturesof most immediate interest to gaseous instrumentation. The ceramics have beenproduced in a region of mass concentrations far from what has been usuallyexplored in literature: optimal characteristics are achieved for Fe$_2$O$_3$concentrations of 75%wt (LAr boiling temperature), 35%wt (LXe boilingtemperature), and 100%wt (room temperature). The nine order of magnitudeenhancement observed for the electrical conductivity of the mixed phasesrelative to that of pure Fe$_2$O$_3$ is startling, however it can bequalitatively understood based on existing literature. Plates of 4 cm x 4 cmhave been manufactured and, prior to this work, operated in-detector at the LXeboiling point (165 K), demonstrating spark-free operation. Preliminary resultsobtained for the first time on a spark-protected amplification structure(RP-WELL) at around the LAr boiling point (90 K) are now presented, too.
