A core-shell ceramic particulate is provided. The core-shell ceramic
particulate comprises a core particulate structure comprising a plurality
of primary particulates and a plurality of primary pores; and a shell at
least partially enclosing the core particulate structure. Each of the
primary particulates comprises a plurality of secondary particulates and
a plurality of secondary pores; and the shell comprises a plurality of
tertiary particulates and a plurality of tertiary pores. A method of
making a core-shell ceramic particulate is provided. The method comprises
the steps of providing a core particulate structure comprising a
plurality of primary particulates and a plurality of primary pores
wherein each primary particulate comprises a plurality of secondary
particulates and a plurality of secondary pores; and disposing a shell
comprising a plurality of tertiary particulates and a plurality of
tertiary pores onto the core particulate structure.
