Ventaja del crisol de óxido de aluminio.
1.Crisol de óxido de aluminioTambién se llama crisol de corindón.
2.Crisol de óxido de aluminioLa forma es principalmente cilíndrica, cónica, cuadrada, etc.
3.Crisol de óxido de aluminioTiene buena resistencia química y a la temperatura y puede usarse durante mucho tiempo. A 1650°C, también se puede utilizar a temperaturas de hasta 1800°C. Pero sólo para uso a corto plazo.
4. Elcrisol de óxido de aluminiotiene buena resistencia al calor y enfriamiento rápidos y no es fácil de reventar.
5. Elcrisol de óxido de aluminioEstá formado por fundición deslizante, la densidad es alta.
6.Crisol de óxido de aluminioTiene buen aislamiento a altas temperaturas y resistencia mecánica en atmósferas oxidantes y reductoras.
Aplicación del crisol de óxido de aluminio.
1. Crisol de óxido de aluminioSe puede utilizar en diversos análisis de muestras de metales y no metales de laboratorio y materiales de fusión.
2. Crisol de óxido de aluminioSe puede utilizar en hornos lanzadera y hornos de placa de empuje para quemar materiales de color, colorantes, fritas, pigmentos, materiales luminiscentes, etc.
3. Horno experimental pequeño, fórmula de ajuste del horno eléctrico experimental y otros fines.
4. Fusión de metales, metales preciosos, vidrios ópticos, análisis y cocción de materias primas minerales como tierras raras.
5. Cocción de productos de alta temperatura como polvo cerámico.
