Abstract
Phase change materials are the category of materials that release or absorb enough energy during phase change transformation to provide heating or cooling. Divided into two principal classes of organic and inorganic, these materials find a wide range of uses in commercial applications of casting where stable temperature and heat storage are a requirement. In this research work, application of inorganic phase change materials having significantly elevated temperature zone, especially within metal casting processes, has been discussed. Phase change material with high enthalpy of fusion and high melting point can be used for metal casting, but in a limited temperature range (between 200°C and 1300°C). In sand casting, inorganic PCM has the potential to be used as chills to provide directional solidification. Despite having advantages, inorganic PCM comes with major disadvantages, that is, toxicity, corrosivity, supercooling, and low thermal expansion. Few solutions to overcome these problems have been discussed in this research paper. Future research is required to reduce the disadvantage to a low level, so that PCM can be used in application where elevated temperature is achieved.

Directions is work comprehensively reviews the recent advances in the Phase change material (PCM) and critically analyses use of PCM in the processes of metal casting. e major conclusions of this article are as follows: (1) High enthalpy of fusion and high melting point of inorganic PCMs will absorb heat for long time and satisfy the elevated temperature requirement of metal casting
(2) ese inorganic phase change materials have high fusion enthalpy and melting point; they can potentially be used as chills in sand casting process
Summary
Metal imitation is a modern process with ancient seats. In the metal molding process, the final mold is produced by pouring molten metal into the mold hole, where the molten metal cools and the final extract is extracted from the skin. It is used to make many metal objects that are used in our daily lives: car tires, train wheels, light poles, school buses, and much more. Steel foundations rely on the recycling of iron as a viable source of underdeveloped material, which greatly reduces waste disposal that ends up in the landfill
