WebThe term crystallite is a structural parameter defined as a crystal volume with different orientation from its neighbors. From: Physical Metallurgy (Fifth Edition), 2014 Related … WebA crystallite is a domain of solid-state matter that has the same structure as a single crystal. Metallurgists often refer to crystallites as " grains ". Solid objects that are large enough to see and handle are rarely composed of a single crystal, except for a few cases ( gems, silicon single crystals for the electronics industry, certain ...
