Classification		Advantages	Disadvantages
Organic PCMs	Paraffin	Availability in a broad range of temperatures	Low thermal conductivity
		Chemically stable and inert	Moderately flammable
		High heat of fusion	Relatively high costs of pure paraffins
		No or minor supercooling	Noncompatible with plastic containers
		Noncorrosive	–
	Non‐paraffin	High heat of fusion	Low thermal conductivity
		No or minor supercooling (depending on form of application)	Flammable
			Instability at high temperatures
Inorganic PCMs	Salt hydrate	Sharp melting point	Phase separation
		High thermal conductivity	Cycling stability
		High heat of fusion per unit	Supercooling
		Small volume change	Corrosive
		Low cost
	Metal	Sharp melting points	Corrosive
		High thermal conductivity	Toxicity, environmental concerns
		Small volume change
