Abstract: Silicates are one of the most primitive, refractory dust species known to have been present within the pre-solar nebula. Calcic pyroxenes ((Ca,Mg)Si2O6) and forsteritic olivines (MgSiO4) are found within meteorites as characteristic mineral components of Calcium Aluminium Inclusions (CAIs) [1]. The chemical structure of such materials is directly related to their formation history and subsequent evolution, therefore studying the physical properties of these minerals can provide a diagnostic with which to gain valuable information about the environmental conditions within the early solar nebula, and the processes leading to their formation
