This paper reports on the use of Jack bean meal as an alternative source of urease for direct coagulation casting (DCC) processes. Al2O3 suspensions were prepared to compare the effect of Jack bean meal and pure urease on the hydrolysis of urea, the slurry coagulation rate, and the mechanical properties of consolidated bodies. Results indicate that the Jack bean meal is a promising economic alternative for the consolidation of ceramic parts, mainly because of its lower susceptibility to enzyme deactivation when exposed to room temperature and relatively humid environments.
