Mechanochemical synthesis of Pb₂MgWO₆piezoceramics with alloying additives

Abstract

Pb2MgWO6 was prepared using mechanochemical activation and sintering in a temperature range of 600-1000ºÑ in three ways: 1) from oxides of the corresponding metals, 2) using MgWO4 precursor; and 3) in the presence of over-stoichiometric amounts (1wt.% and 2wt.% ) of Li2CO3 alloying additive.
