ABSTRACT:
Ceramic bodies having conically shaped pores are produced by electrophoretic deposition from aqueous ceramic particle suspensions. The dense ceramic bodies may be fabricated in the form of tubes having the pores radiating inward or outward. Alternatively, other shapes may be fabricated. The bodies are useful as filters, burner elements, catalysts supports, etc.
