ceramic

· JVASP-49791· ScTlO2

ScTlO2 is an experimental ceramic compound combining scandium, thallium, and oxygen, belonging to the mixed-metal oxide family. While not yet established in mainstream industrial production, this material is primarily of interest in advanced materials research for potential applications requiring high density and notable elastic properties in a ceramic matrix. The thallium-containing composition makes it a subject of investigation in specialized ceramics research, though practical adoption remains limited due to thallium's toxicity concerns and the material's nascent development stage.
