《GB/T 5069.6-2001镁质及镁铝(铝镁)质耐火材料化学分析方法 铬天青S光度法测定氧化铝量》由TC193(全国耐火材料标准化技术委员会)归口,主管部门为国家标准化管理委员会。
本标准规定了铬天青S光度法测定氧化铝量的方法。本标准适用于镁质耐火原料及制品中氧化铝量的测定,测定范围:0.10%~2.00%。本标准不适用于二氧化钛的质量分数大于0.1%的镁质耐火材料。
Scope
This standard specifies the method for determining the amount of alumina by chrome azure S photometry. This standard applies to the determination of the amount of alumina in magnesia and magnesium-aluminum (aluminum-magnesium) refractory raw materials and products, and the measurement range is 0.10% to 2.00%. This standard does not apply to magnesia refractories with a mass fraction of titanium dioxide greater than 0.1%.
