Merge from Decomposition temperature
Would be useful to have on the same page. Merge - Jack (talk) 03:59, 23 October 2006 (UTC)

Unless the list of materials and temperatures grows too big, merge. 84.160.245.126 17:28, 19 November 2006 (UTC)
 * What lists? - Jack (talk) 17:52, 24 December 2006 (UTC)

There is an Incorrect statement: "Supposedly, the compound with the highest decomposition temperature is carbon monoxide—~7000 F, higher than the surface temperature of the sun" I can't edit it, but sun's surface temperature is ~5,400 ºC (9,800 ºF), http://www.daviddarling.info/encyclopedia/S/Sun.html OR 5,780 K (5,510 °C) http://en.wikipedia.org/wiki/Sun.. Regardless of the source, 7k F is not 9.8k F. Keeping it SI would be preferable as well -- For consistency. I would remove the sentence entirely, because I cannot find a source to verify that statement. —Preceding unsigned comment added by 199.243.188.170 (talk) 01:30, 12 July 2009 (UTC)

Examples in article are wrong, they are not complex organic compounds
According to Encyclopædia Britannica thermal decomposition is "a breakdown of complex organic compounds without oxidation". The examples given in this article, calcium carbonate and copper carbonate, are not complex organic compounds. The examples should be replaced or removed. --Tunheim 12:26, 16 January 2007 (UTC)


 * Encyclopaedia Britannica isn't an authority on anything, certainly it's in no position to provide definition for terms coined and commonly used by scientists. The IUPAC definition of decomposition, http://goldbook.iupac.org/D01547.html, coupled with the obvious definition of thermal would result in a definition that sounds something like: Thermal decomposition is the decomposition of a single phase into into two or more phases at elevated temperature. The example is perfectly valid. Encyclopaedia Britannica, HA, right.GreatMizuti 04:19, 28 October 2007 (UTC)

example
Is this the process by which hydrogen appears in nuclear reactors such as VHTR and Fukushima? If so, those would exemplify fairly simply the utility and the significance of the topic process. Cesiumfrog (talk) 02:41, 15 March 2011 (UTC)

I added the section for further applications as I believe this will be useful to help further demonstrate how thermal decomposition affects real-world scenarios. Meganmwolf (talk) 00:21, 30 September 2021 (UTC)

I feel the figure is incorrect and should be removed completely. It implies that oxidation, or combustion, is thermal decomposition. But oxidation builds larger molecules rather than breaking them down. In addition it implies that ignition automatically occurs after pyrolysis; and although pyrolytic reactions occur in say a fireplace prior to seeing a flame (gases are driven from wood), pyrolysis on process/engineering level is done in the complete absence of oxygen and as a result, there is no combustion/ignition.
