The thermal stability and crystallization behaviors of La2O3 containing B2O3-CaOeAl2O3 glass wasteforms were investigated to evaluate the stability of waste form during emergencies in deep geologicaldisposal. For glasses containing 15% La2O3, LaBO3 phases were observed as major crystals from 780 Cand exhibited needlelike structures. Al, Ca, and O were homogeneously distributed throughout the entirespecimen, while some portions of B and La were concentrated in some parts. By differential thermalanalysis at various heating rates, the activation energy for grain growth and the crystallization rate ofLaBO3 were calculated to be 12.6 kJ/mol and 199.5 kJ/mol, respectively. These values are comparable toother waste forms being developed for the same purpose.
