SILICON-NITRIDE-CONTAINING SEPARATING LAYER HAVING HIGH HARDNESS
PROBLEM TO BE SOLVED: To provide a shaped body comprising a substrate with a firmly adhering silicon nitride-containing separating layer, which is resistant to abrasion, impact, and scratch as well as thermally stable, for use as melt crucibles used in silicon processing of battery for a solar cell.SOLUTION: A shaped body comprises a substrate with a firmly adhering separating layer. The separating layer comprises: 92 to 98 wt.%, preferably 94 to 98 wt.%, further preferably more than 95 wt.% and 97 wt.% or less, of silicon nitride (SiN); 2 to 8 wt.%, preferably 2 to 6 wt.%, further preferably 3 to less than 5 wt.%, of silicon dioxide (SiO); and up to 150 ppm of a residual content of a dopant including an alkali metal compound in the form of flux. The separating layer has a total oxygen content of less than 5 wt.% and a hardness of at least 10 HB 2.5/3 according to DIN EN ISO 6506-1.SELECTED DRAWING: None
