Abstract
Sposób wytwarzania wysokoogniotrwałego tworzywa polega na tym, że uprzednio otrzymane półprodukty w postaci brykietów z cyrkonianu wapnia w ilości 5 - 95% masowych oraz stabilizowanego jonami magnezu tlenku cyrkonu w ilości 5 - 95% masowych poddaje się wstępnemu rozdrobnieniu do uziarnienia poniżej 2 mm, następnie mieleniu na mokro. Uzyskaną zawiesinę proszku poddaje się suszeniu i granulacji, po czym formuje się kształtki z otworem przelotowym stosując prasowanie jednoosiowe z ewentualnym dogęszczaniem izostatycznym, a uzyskany wyrób wypala się w temperaturze 1600 - 1800°C. Cyrkonian wapnia w postaci kształtek otrzymuje się na drodze wspólnego przemiału kamienia wapiennego z tlenkiem cyrkonu, wprowadzanym w ilości zapewniającej pełne przereagowanie tlenku wapnia na cyrkonian wapnia, po czym z mlewa formuje się kształtki, które poddaje się dwustopniowej obróbce termicznej. Pierwszy etap obróbki polega na kalcynacji w temperaturze 1000 - 1200°C, a drugi na wypalaniu w temperaturze 1650 - 1800°C lub topieniu w temperaturze powyżej 2345°C. Natomiast stabilizowany jonami magnezu tlenek cyrkonu otrzymuje się poprzez poddanie mieszaniny tlenków cyrkonu i magnezu wypaleniu w temperaturze powyżej 1700°C lub topieniu w temperaturze powyżej 2700°C, przy czym MgO wprowadza się w ilości 10 - 15% molowych w stosunku do masy ZrO2.The method of producing highly refractory plastic consists in the fact that previously obtained semi-finished products in the form of briquettes from calcium zirconate in an amount of 5 - 95% by mass and stabilized with magnesium ions of zirconia in an amount of 5 - 95% by mass are subjected to preliminary grinding to a grain size of less than 2 mm, followed by grinding wet. The obtained powder suspension is subjected to drying and granulation, then shaped bodies with a through-hole are formed using uniaxial compression with optional isostatic densification, and the obtained product fires at a temperature of 1600 - 1800 ° C. Calcium zirconate in the form of shaped parts is obtained by joint milling of limestone with zirconium oxide, introduced in an amount ensuring full conversion of calcium oxide into calcium zirconate, after which the mulch is formed into shapes that undergo a two-stage thermal treatment. The first stage of treatment consists of calcining at a temperature of 1000 - 1200 ° C, and the second stage of firing at a temperature of 1650 - 1800 ° C or melting at a temperature above 2345 ° C. On the other hand, zirconia stabilized with magnesium ions is obtained by subjecting a mixture of zirconia and magnesium oxides to burning at a temperature above 1700 ° C or melting at a temperature above 2700 ° C, with MgO being introduced in an amount of 10 - 15 mol% based on the weight of ZrO2.
