Abstract: This paper presents thermal effect characterization of the explosive tritonal 80/20 (80 mass % of TNT and 20 mass % of Al). Explosive charges were prepared by casting technological process. Quality of TNT was examined according to SORS 1133 at the company „Prva Iskra – Namenska a.d.“ (Baric, Serbia). Quality of aluminum was examined at the Military Technical Institute by measuring the weight mean diameter and observing it with Scanning Electron Microscope. Chemical composition by segment, density, impact and friction sensitivity and detonation velocity of prepared explosive charges were determined. Detonation thermal effects of tritonal and pure cast TNT were observed by optical pyrometer Sensortherm Metis H311. Thermal effects of tritonal and pure cast TNT were compared through analysis of data obtained by optical pyrometer, and the results are shown in this paper.

Keywords: tritonal, TNT, SEM, thermal effect, optical pyrometer.
