Rare earth powder used to produce ceramic material

Rare earth powder used to produce ceramic material

Rare earth powder has an isoelectric point of < pH 9 in aqueous dispersion. Production of the rare earth powder is also claimed, in which SiO2 is deposited by hydrolysing silicic acid esters and/or other hydrolysable silicon compounds from silica sol and/or aqueous solutions to rare earth powder...

Beschreibung
Zusammenfassung:Rare earth powder has an isoelectric point of < pH 9 in aqueous dispersion. Production of the rare earth powder is also claimed, in which SiO2 is deposited by hydrolysing silicic acid esters and/or other hydrolysable silicon compounds from silica sol and/or aqueous solutions to rare earth powder present in aqueous and/or alcoholic dispersion
