Alternate Names: C1251 Fritte, C 1251 Fritte, Ceradel Frit 1251
This analysis is guessed, the manufacturer calls it a lead monosilicate and provides the approximate chemistry of (SiO2 - 15-40%, PbO 60-100%. However since the lead monosilicate analysis is universally 1:1 lead:silica that is what we have assigned here. We have another source that confirms that.
|Materials||Ceradel Frit C 1249|
|Materials||Lead Bisilicate Frit|
|Materials||Lead Monosilicate Frit|
Frits can contain 1% or 80% PbO so this category can be misleading, check the chemistry to find out.
|Co-efficient of Linear Expansion||83x10-7 (20-300C)|
|Frit Softening Point||900-1100C|
