Description
Известен высокоогнеупорный .материал на основе твердого раствора ZrOo-MgO с содержанием 10-15 мол. о/о окиси .магни .The high-refractory material is known. It is based on the solid solution ZrOo-MgO with a content of 10-15 mol. O / O oxides. Magnesium.
Существующий огнеупор не термостабилен. При длительном изотермическом нагревании при температуре 1100-1300°С циркониевомагниевый твердый раствор распадаетс на двуокись циркони и окись магни .Existing refractory is not thermostable. With prolonged isothermal heating at a temperature of 1100-1300 ° C, the zirconium-magnesium solid solution decomposes into zirconium dioxide and magnesium oxide.
Цель изобретени - повысить термостабильность .The purpose of the invention is to increase thermal stability.
Достигаетс это тем, что предложенный материал дополнительно содержит 2-4 мол. % окиси иттри .This is achieved by the fact that the proposed material additionally contains 2-4 mol. % yttria.
Материал .можно изготовить любым из существующих способов синтеза (обжигом смесей окислов, обжигом легкоразлагающихс солей, coocaжJ ;eниeм из растворов). Издели изготовл ют прессованием, литьем, экструзией . Обжиг производ т при температуре не ниже 1 600°С в зависимости от назначени издели .The material can be manufactured by any of the existing methods of synthesis (roasting of mixtures of oxides, roasting of easily decomposable salts, co-synthesis; from solutions). The products are made by pressing, casting, extrusion. Firing is performed at a temperature not lower than 1 600 ° C, depending on the intended use of the product.
Свойства материала приведены в таблицеMaterial properties are listed in the table.
