Scope

This standard specifies the chemical analysis methods for refractory materials containing carbon, silicon carbide and nitride and raw materials. The items analyzed in this standard are as follows: volatile matter (VOL); loss on ignition (LOI); total carbon content (TC); free carbon content (FC); silicon carbide content (SiC); total nitrogen content (TN); The amount of silicon (Si₃N₄); the amount of free silicon (F.Si); the amount of free aluminum (F.Al); the amount of silicon dioxide (SiO₂); Aluminum content (Al₂O₃); iron oxide content (all valence iron is calculated as Fe₂O₃); titanium dioxide content (TiO₂ ); the amount of calcium oxide (CaO); the amount of magnesium oxide (MgO); the amount of potassium oxide (K₂O); the amount of sodium oxide (Na₂O); the amount of phosphorus pentoxide (P< Subscript 2>O₅); zirconium oxide (hafnium) amount (ZrO₂+HfO₂); manganese oxide amount (all valences of manganese are calculated as MnO); Chromium content (Cr₂O₃). See Table 1 for the measurement range of the analysis items in this standard.
