Abstract: Enstatite (MgSiO3) ceramic powders were synthesised by a low-temperature initiated self-propagating, gas-producing solution combustion process. The prepared powders were characterised by powder X-ray diffraction, scanning electron microscopy and Brunauer-Emmer-Teller specific surface area measurements. Defect centres induced by radiation were studied using the techniques of thermoluminescence (TL) and electron spin resonance (ESR). A well-resolved glow with peak at 178 degrees C and a shouldered peak at 120 degrees C were observed. Two defect centres were identified by ESR measurements, which were carried out at room temperature, and these were assigned to an O- ion and F+ centre. The O- ion (hole centre) appears to correlate with the main TL peak at 178 degrees C.
