Abstract
Opisano sposób syntezy bezwodnych zwiazków fluorków K2LnF5, gdzie Ln oznacza wszystkie trójwartosciowe jony lantanowców Ln = La - Lu, przy wykorzystaniu znanego tygla grafitowego oraz atmosfery inertnej. Sposób charakteryzuje sie tym, ze mieszanine stechiometryczna zlozona z 2KF oraz LnF3 homogenizujemy, a nastepnie umieszczamy na czas od 2 do 6 dni, w tyglu grafitowym ulokowanym w piecu rozgrzanym do temperatury od 600-650°C.The method of synthesis of anhydrous K2LnF5 fluoride compounds was described, where Ln stands for all trivalent lanthanide ions Ln = La - Lu, using a known graphite crucible and inert atmosphere. The method is characterized by the fact that the stoichiometric mixture consisting of 2KF and LnF3 is homogenized and then placed for 2 to 6 days in a graphite crucible located in a preheated oven to a temperature of 600-650 ° C.
