Study on characteristics and sintering behavior of W-Ni-Co

Chemical gradient associated with the solubility of the W and γ(Ni, Co) phase is important in dominating the early stage of sintering. In case of the secondary ball milling, tungsten grains have a low mutual solubility in the binder phase and thus there is little sintering due to chemical gradients prior to liquid formation.This work aims at increasing solubility and dissolution rate of ziprasidone free base—Biopharmaceutics Classifaction System (BCS) class II compound.
