Abstract This work presents the deconvolution of thermoluminescent (TL) glow curves, by using logistic asymmetric functions, sintered pure alumina matrices under two different conditions: 1000 °C/3h (NALO) and °C/6h (ALO), also, cerium-doped matrix with 0.1 wt.% at (NALOCe0.1). Sintering treatments induced a remarkable change in TL kinetics consequently curve shape, terms number traps initially...

New innovative approach to fabricate porous alumina ceramics by cold sintering process (CSP) is presented using NaCl as pore forming agent. The effects of CSP and post-annealing temperature on the microstructure mechanical strength were investigated. Al2O3–NaCl composite with bulk density 2.92 g/cm3 was compacted firstly then a structure formed at 1200°C–1500°C for 30 min. Brazilian test method...

A basic alumina-spinel low cement castable (LCC) composed of sintered bauxite, reactive alumina, calcined alumina, calcined magnesia, microsilica, and high alumina refractory cement was prepared (castable A) to which 5% sodium hexa-meta phosphate was later added (castable B) to prepare samples for heat treatment at 110ºC, 900ºC, and 1400ºC. Bulk Density (BD), Apparent Porosity (AP), and Cold Cr...
