标准范围

ISO 21068-3:2008规定了碳化硅原材料和耐火材料产品中总氮和氮的测定方法，计算为氮化硅、总氧、游离金属和氧化成分。它仅适用于未与氮结合的碳化硅材料。EN 12698-1涵盖了氮化物结合碳化硅耐火材料。

ISO 21068-3:2008 specifies methods for the determination of total nitrogen and nitrogen calculated as silicon nitride, total oxygen, and free metallic and oxidic components in silicon carbide raw materials and refractory products.It applies only to silicon carbide materials that are not bonded with nitrogen. Nitride-bonded silicon carbide refractories are covered in EN 12698-1.
