1. A process for manufacturing a ceramic component, wherein the process comprises:
manufacturing a ceramic powder with binder comprising at least one additional element or compound by depositing the at least one additional element or compound on a base ceramic powder with binder by at least one selected from the group consisting of:
a physical vapor deposition (PVD),
a chemical vapor deposition (CVD), and
an atomic layer deposition (ALD),
after performing the depositing of the at least one additional element or compound,
performing a provisional shaping of the ceramic powder with binder comprising the at least one additional element or compound, then
debinding the provisionally shaped ceramic component including eliminating organic compound(s) followed by sintering the ceramic component.
