Abstract: A core-shell particle includes a core and a shell that is wrapped around the core. The core includes aluminum nitride. The shell includes aluminum and a dopant, and the dopant is yttrium, calcium, magnesium, lanthanum, niobium, titanium, copper, or a combination thereof. The aluminum and the dopant in the shell have a weight ratio of 90:10 to 99.9:0.1. The core-shell particle can be sintered to form a ceramic bulk.
