The latent heat of crystallisation of sodium chlorate

Click For Summary
SUMMARY

The discussion focuses on the use of a saturated solution of sodium chlorate as a thermal storage medium for maintaining hot water supply in residential or marine settings. Key concerns include the latent heat of crystallization of sodium chlorate and its potential corrosive effects on storage containers. The participant seeks information on the heat capacity per gram of sodium chlorate crystals and the compatibility of stainless steel vacuum-insulated tanks with the solution. References to relevant research articles provide additional insights into these issues.

PREREQUISITES
  • Understanding of latent heat and thermal storage concepts
  • Knowledge of sodium chlorate properties and crystallization
  • Familiarity with material compatibility, especially regarding corrosive substances
  • Basic principles of solar heating systems
NEXT STEPS
  • Research the latent heat of crystallization of sodium chlorate
  • Investigate the corrosive effects of sodium chlorate on stainless steel
  • Explore thermal storage solutions for solar heating systems
  • Review engineering studies related to sodium chlorate applications
USEFUL FOR

This discussion is beneficial for engineers, solar heating system designers, and anyone interested in thermal storage solutions using sodium chlorate, particularly in residential or marine applications.

I am a retired electronic engineer and no scientist. I am considering the use of a saturated solution of sodium chlorate as a thermal store. My problems are: 1/ I have no idea of the quantities involved in terms of heat/gram of crystals. My intention is to maintain a supply of hot water for a house or boat using solar heating. 2/ I don't know of any corrosive effects of such a solution on the container. Would a stainless steel vacuum-insulated tank work?

I suspect it would be rather corrosive though.
Thanks, it seems to have at least one of the answers. It is way out of my comfort zone so I will have to study it for engineering rather than academic truths. Thanks again.
