Abstract

In this paper we report the discovery of a new structural family for use in ultra-low 'α' ceramics. The prototype composition is Ca0.5Ti2P3O12 abbreviated [CTP] after which the structural family is named. The importance of this family in contrast to the eucryptite-spodumene family is the enormous range of substitutions which are possible, permitting one to control 'α' continuously over a wide range of temperature. Different compositions exhibit near zero thermal expansion in different temperature ranges.
