Properties
Thermophysical	Nucleation and crystal growth	Chemical	Economics
(i) Melting temperature; (ii) High latent heat of fusion; (iii) High specific heat; (iv) High thermal conductivity; (v) Small volume change on phase transformation and small vapor pressure; (vi) Congruent melting of the PCM for a constant storage capacity; (vii) Reproducible phase change	(i) High nucleation rate to avoid sub cooling of liquid phase; (ii) High rate of crystal growth	(i) Complete reversible freeze/melt cycle; (ii) No degradation after a large number of freeze/melt cycle; (iii) No corrosiveness; (iv) Nontoxic,; (v) Non flammable; (vi) Nonexplosive	(i) Abundant; (ii) Available; (iii) Cost effective; (iv) Easy recycling and treatment; (v) Good environmental performance
