  <dc:description>&lt;p&gt;&lt;span&gt;The addition of quercetin, an organic flavone (C&lt;/span&gt;&lt;sub&gt;15&lt;/sub&gt;&lt;span&gt;H&lt;/span&gt;&lt;sub&gt;10&lt;/sub&gt;&lt;span&gt;O&lt;/span&gt;&lt;sub&gt;7&lt;/sub&gt;&lt;span&gt;), to aqueous solutions containing silica and aluminum and adjusted to final&amp;nbsp;&lt;/span&gt;&lt;i&gt;p&lt;/i&gt;&lt;span&gt;H's from 6.5 to 8.5 produced a 1 : 1 alumninosilicate precipitate which, after 6 to 16 months of aging in solution at 25&amp;deg;C, contained as much as 5 percent well-formed&amp;nbsp;&lt;/span&gt;&lt;span class="search-term-highlight"&gt;kaolinite&lt;/span&gt;&lt;span&gt;&amp;nbsp;plates. Similar solutions containing no organic material produced relatively amorphous precipitates with the same composition and stability (standard free energy of formation = -897&amp;plusmn;1 kilocalories per mole) but with substantially smaller amounts of crystaline material even after 2 years of aging.&lt;/span&gt;&lt;/p&gt;</dc:description>
