In addition to automated SEM techniques, MTI uses SEM morphological analysis to fully characterize materials. While automated SEM analysis provides quantified information about chemistry, size, and amount of phases and particles present, morphological analysis provides information about the physical relationships of the size, crystallinity, and juxtaposition of the phases present.
For example, a morphological investigation of deposits provides insight about the characteristics of the liquid phases responsible for growth of necks (particle-to-particle bonding) between deposited particles and the formation of a sticky-deposit surface capable of capturing impacting particles.
The table below provides morphology data from the above two images.
