Synthesis of caprolactamates of group II metals

Observation of chemical reactions between alkaline-earth oxides and tungsten at high pressure and high temperature

“…In addition, no chemical reaction was detected when W was heated together with MgO during 10 min. This observation suggests that the reactivity of the AeO and tungsten increases in the order MgoCaoSroBa, which is in agreement with previous observations of Chekulaeva et al [21].…”
