Radiative transfer theory explained most of the observed variations in illuminant functioning. Effects of spin, liner thickness and binders have been analyzed, and application of the results has been used to improve illuminant performance and solve production problems.<\/p>\n<p align=\"left\"><strong>Keywords:<\/strong> illuminant, photoflash, efficiency, magnesium, sodium, nitrate, binder, radiative transfer<\/p>\n<hr \/>\n<p><em><strong>Ref:<\/strong> JPyro, Issue 19, 2004, pp53-60<br \/> (J19_53)<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>David R.
