Abstract

<abstract abstract-type="graphical"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Si–SiC–ZrB₂ are produced by the reactive infiltration with molten silicon in porous SiC–C–ZrB₂ preforms. It is observed that oxidized Si–SiC–ZrB₂ ceramics present a layered structure composed of an outer layer of silica and a borosilicate glass intermediate layer with ZrO₂ particles and the unoxidized bulk material. The graphs show that the passivation is very effective already after 5 min of oxidation. The thermograms do not vary significantly when the oxidation times are increased. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4sr4hrwz" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
