“…The long-lasting mechanic activation of the raw material mixture witha stoichiometric composition consisting of SrCO 3 , SiO 2 , and Al 2 O 3 over 12 hours enabled an almost complete binding of the starting components into a Sr-anorthite phase at a firing temperature of 1,100 °C. However, the degree of compaction and the mechanical properties of synthesized materials were also not sufficient [16].…”
