Abstract
A novel process is disclosed for producing a fracture-free shaped ceramic green body which comprises casting an aqueous suspension of hydroxylapatite, whitlockite or a mixture of these having a high water content and high drying shrinkage in an impervious mold, the cavity surfaces of which are coated with an inert water-immiscible lubricant; drying the casting under controlled conditions of temperature and humidity and removing adsorbed lubricant from the resulting dried green body.
