説明

<jats:p>Fused silica rods were exposed to molten aluminum and the rate of penetration of the reaction into the silica was measured over a range of temperatures. The reaction obeys the equation:</jats:p> <jats:p> <jats:disp-formula> <jats:graphic xmlns:xlink="http://www.w3.org/1999/xlink" position="anchor" xlink:href="urn:x-wiley:00027820:media:JACE101:JACE_101_mu1"> <jats:alt-text>image</jats:alt-text> </jats:graphic> </jats:disp-formula> </jats:p> <jats:p>Three phases of alumina are formed during the reaction. The Group V elements, bismuth and antimony, markedly affect the rate of reaction. It is proposed that they form a lamellar surface compound with oxygen and water already absorbed on the silica surface. This compound then controls the reaction kinetics.</jats:p>
