TREATMENT OF MELT QUENCHED ALUMINOSILICATE GLASS SPHERES FOR APPLICATION AS PROPPANTS VIA DEVITRIFICATON PROCESSES |
摘要 |
<p>A process for increasing toughness of glass particulates is provided. The process includes providing an aluminosilicate glass particulate, the glass particulate generally having the form of a sphere, and heating the glass particulate to a temperature greater than 6000C for a predetermined time. Thereafter, the glass particulate can be cooled to ambient temperature and the heating step can alter the failure mechanism of the glass particulate from a high energy failure that produces generally fine powder to a lower energy failure that produces generally large fragments. The glass particulate can be an amorphous glass particulate and may or may not have a nominal composition that corresponds to rhyolite, basalt, tholeiite, olivine and/or andesite.</p> |
