Abstract
The use of diphasic or multiphasic composites, involving one negative α phase to control and lower the thermal expansion of a ceramic for substrate, laser mirror and anti-thermal shock applications, was studied. The two phases thermodynamically stable with each other - one with negative α and the second with positive α were mixed, sintered and characterized for thermal expansion behaviour. The negative-α phase was selected from the [NZP] or [CTP] structural family. Specific systems including NaZr2P3O12, CaZr4P6O24 + Nb2O5, GdPO4, ZrSiO4, Mg3(PO4)2, MgO and ZnO were investigated. Several compositions exhibited a near-zero expansion profile over a wide temperature range.
