Phase Change Materials (PCMs) or Thermal Salts are "latent" energy storage materials. They use chemical bonds to store and release heat. The thermal energy transfer occurs when a material changes from a solid to a liquid, or from a liquid to a solid. This is called a change in state, or "phase." Ice changes phase when heated at 0 deg C and is converted to water. Ice is an excellent PCM.
It absorbs a large amount of heat in the process of changing from solid to liquid phase and this results in cooling of the surroundings. But what if you require this heat at a temperature other than zero? Thermal Salts can give out latent heat at a wide range of temperatures from sub-zero to several hundred degrees. This 'heat-on-demand' requirement is satisfied by PCMs which work at specified temperatures. We have developed a wide range of Thermal Salt for different applications and our team of scientists and engineers can arrive at a customized PCM solution for your unique need.
PCMs can be broadly classed as Organic and Inorganic.
Organic PCMs:
Organic Thermal Salt can be Aliphatic or Other Organics. Users rarely specify the use of Organic PCMs. Latest TM can offer Organic PCMs in low temperature
range. Organic items are expensive and they have average Latent Heat per unit volume and low density. Most items in organic range are combustible in nature. They also
have a wider range of Melting Point. Some customers specify organic PCM and we offer them as per their requirement. You need specify the desired Melting Point only.
Inorganic PCMs:
Inorganic Thermal Salt are generally Hydrated Salt based materials. Academicians are likely to misguide you into using pure hydrated salts like Sodium Sulphate
Decahydrate and so on. Hydrated salts have a number of hydrates and an anhydrous form leading to stratification of material and loss of Latent Heat recovery with time.
Hydrated salts also have a sub-cooling tendency. Old generation Thermal Salt manufacturers managed to add performance-enhancing agents. These additives do help in
delaying the degradation of the thermal salt for say 100 cycles or thereabout. However, they do not address the basic reasons due to which sub-cooling and degradation
happens. Earlier researchers emphasized that it is beneficial to use impure grades of base material as it promotes the nucleation and prevents sub-cooling. However,
impurities also promoted nucleation of undesirable hydrates leading to stratification. Experts on crystallography have managed to identify the “Preferred Crystal
Nucleation” method. It consists of a “Cold Finger” that nucleates and promotes the growth of desired crystals and “Detoxification” or “Selective Elimination” whereby
any impurity that promotes the growth of undesirable crystals is removed. The current methods of Thermal Salt manufacturing are like the new generation “Combination
Drugs”.
