The study of thermal conductivity in materials is essential for the development of devices in fields such as electronics, thermoelectrics, and pyrotechnics. This work investigates the thermal conductivity of gel-grown barium oxalate (BaC₂O₄) crystals at two specific temperatures: 328 K and 336 K. The crystals were synthesized using the single diffusion gel technique, with agar-agar serving as the gelling medium. Thermal conductivity measurements were carried out using the steady-state divided bar method. At 328 K, the thermal conductivity was measured to be 3.602 W/m·K, which decreased to 3.103 W/m·K at 336 K. This decline is consistent with theoretical predictions and is attributed to increased phonon- phonon scattering at higher temperatures. The findings provide valuable insights into the thermal behavior of BaC₂O₄, highlighting its potential utility in temperature-sensitive applications.
