Изобретение относитс к огнеупорной промышленности .The invention relates to the refractory industry.
Известна огнеупорна масса дл изготовлени огнеупорных датчиков (наконечников, тиглей ) на основе АЬОз с добавкой ZrO2. Однако датчики изготовленные из такой массы имеют низкую термостойкость, неста бильные керамические и электрические свойства.A known refractory mass for the manufacture of refractory sensors (tips, crucibles) based on ABOZ with the addition of ZrO2. However, sensors made from such a mass have low heat resistance, unstable ceramic and electrical properties.
Предлагаема масса даполнительно содержит TiO2 лри следующем соотношении компонентов , вес. %:The proposed mass additionally contains TiO2, the following ratio of components, weight. %:
АЬОз95-85ALOZ95-85
ZrOa4--10ZrOa4--10
TiOz1-5TiOz1-5
В качестве исходных материалов используют технический глинозем, обожженный при температуре 1450°С и измельченный в вибромельнице до размера частиц менее 2 мк, и химически чистые ZrOs и TiOs.The raw materials used are technical alumina, calcined at a temperature of 1450 ° C and ground in a vibrating mill to a particle size of less than 2 microns, and chemically pure ZrOs and TiOs.
Массу готов т смешением компонентов в вибромельнице.The mass is prepared by mixing the components in a vibrating mill.
Издели из массы с добавкой парафина изготавливают методом прот жки с .последующим выжиганием св зки и обжигом при температуре 1600-1650°С.Products from the mass with the addition of paraffin are made by the method of drawing with subsequent burning out of the bundle and burning at a temperature of 1600-1650 ° C.
Фазовый состав изделий представлен соединени ми , ZrOo (моноклинна ) н иримес ми стекла сложного состава. Издели имеют следующие свойства: открыта пористость, %О-IThe phase composition of the products is represented by compounds, ZrOo (monoclinic) by glass and composite glass composition. Products have the following properties: open porosity,% O-I
