Abstract Pulse electrodeposition method was used to produce nanocrystalline nickel particles of size ranging from 25 nm from saccharin containing Watts type baths. The advantages of using electrodeposition over other methods for synthesis of these particles are discussed, laying special emphasis on the difference between pulse and d.c. plating techniques. The effect of saccharin concentration on the grain size and orientation is described briefly. The superior properties of the nano nickel particles produced by electrodeposition, like negligible porosity, enhanced electrical conductivity etc., are brought to light in comparison with the properties of conventional microcrystalline particles. The preferred orientation of the deposits progressively changed from a strong (2 0 0)-fiber texture for a saccharin free bath to a (1 1 1) (2 0 0) double fiber texture for a bath containing 10 g l saccharin. These are proved by the XRD micrographs obtained
