Processen er også medvirkende ved visse aspekter af mineralvækst ved udstrømning fra <a href="/wiki/Vulkan" title="Vulkan">vulkaner</a>. Teknikken er forskellig fra <a href="/wiki/CVD" title="CVD">kemisk dampudfældnig</a>, som sædvanligvis indebærer opløsning i molekylære bestanddele (f.eks. SiH<sub>4</sub> → Si + 2H<sub>2</sub>), og som giver ensartede belægninger. </p><p>Teknikken, som populariseredes af professor Harald Schäfer,<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> indebærer en reversibel omdannelse af ikke-flygtige <a href="/wiki/Grundstof" title="Grundstof">grundstoffer</a> og <a href="/wiki/Kemisk_forbindelse" title="Kemisk forbindelse">kemiske forbindelser</a> til flygtige, afledte stoffer.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> Disse flygtige forbindelser passerer gennem en forseglet beholder, typisk et lufttomt glasrør, som er opvarmet. Et sted i røret, hvor temperaturen holdes på et andet niveau, vender det afledte stof tilbage til den oprindelige tilstand, og transportmediet frigives igen. Transportmediet er derfor af <a href="/wiki/Katalyse" class="mw-redirect" title="Katalyse">katalytisk</a> natur. Teknikken kræver, at rørets to ender (som indeholder den prøve, der skal krystalliseres) har forskellig temperatur, hvilket opnås ved anvendelse af særlige elektriske røropvarmere.
