Lanthanumoxysulfid er en uorganisk forbindelse , et oxosalt af metallet af lanthan og hydrosulfidsyre , med formlen La 2 O 2 S. Under normale forhold er det gullig-hvide hexagonale krystaller med en densitet på 5,77 g/cm 3 .

Henter

Kalcinering af lanthan(III)sulfat i en oxygenstrøm ved 750 °C:

{\mathsf {La_{2}(SO_{4})_{3}\ {\xrightarrow {O_{2},750^{o}C))\ \ La_{2}O_{3}\ cdot SO_{3}+2SO_{3}}}

Det resulterende produkt reduceres med brint ved opvarmning:

{\mathsf {La_{2}O_{3}\cdot SO_{3}+4H_{2}\ {\xrightarrow {750^{o}C))\ \ La_{2}O_{2}S +4H_{2}O}}

Egenskaber

Lanthanumoxysulfid danner gullig-hvide ildfaste hexagonale krystaller .
Smelter ved 1940 °C.
