Abstract: Metal casting to produce solid objects is a manufacturing process that has been carried out for over 5000 years, with investment casting being one of the oldest known methods of metal shaping. The investment casting has its own advantages over the other method of casting. The investment casting process has been increasingly used to manufacture components for the different industry and has been especially successful in the manufacture of single turbine blades. The method itself has considerable advantages in the manufacture of components of consistency and the main advantages of precision, flexibility and honesty. The process is therefore one of the most cost-effective methods of forming a wide range of metal components. Nevertheless, environmental and economic stresses have contributed to the industry's need to improve current casting efficiency, reduce production costs and explore new process markets. This paper aims at summarizing current ceramic developments and exploring possible methods for improving shell performance
