前言

本文件按照GB/T1.1—2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规

定起草。

本文件代替GB/T9489—2008《刚玉粉化学分析方法》。与GB/T9489—2008相比，除结构调整

和编辑性改动外，主要技术变化如下：

a）增加了“警示”（见警示）；

b）更改了“二氧化硅标准溶液”的浓度及配制过程容量瓶体积（见5.3.8，2008年版的5.3.8）；

c）更改了“Ca、Mg”元素的火焰类型（见6.4.4，2008年版的6.4.4）；

d）更改了原子吸收分光光度法中的“试液制备”（见6.5.1，2008年版的6.5.1）；

e）更改了“硼砂﹘碳酸钠混合熔剂”的加入顺序（见7.5.1、9.5.2.1，2008年版的7.5.1、

9.5.2.1）；

f）增加了二氧化硅标准溶液“放置温度”的要求（见9.5.1、9.5.2.2）；

g）更改了二氧化钛比色法的测定范围（见10.1，2008年版的10.1）；

h）更改了“工作曲线的绘制”中二氧化钛标准溶液的移取体积（见10.5.1，2008年版的10.5.1）。

警示─本文件并未指出与其使用有关的所有安全、健康及环保问题，使用者有责任采取适当的安

全、健康及环保措施，并保证符合国家有关法律、法规的规定。

1范围

本文件描述了刚玉粉中三氧化二铝、氧化钙、氧化镁、二氧化硅、三氧化二铁、二氧化钛、氧化

钾、氧化钠、氯离子、碳和硫、pH值、烧失量的测定方法。

本文件适用于三氧化二铝含量（质量分数）不小于90%的刚玉粉的化学分析。

3术语和定义

本文件没有需要界定的术语和定义。

4总体要求

4.1配制溶液与分析过程中所用水的规格，应符合GB/T6682中规定的三级或三级以上的水。

4.2测定所用试剂，除另有注明外，纯度应优于分析纯。标定与配制标准溶液所用试剂应采用基准试

剂。用金属配制标准溶液时，其纯度应优于99.99%。

4.3分析所用的溶液除特殊指明溶剂外，均系水溶液。

4.4进行“恒重”试验操作时，应在相同温度下灼烧或烘干以及取出、干燥冷却、称重等步骤重复进

行至两次称量之差不大于0.0002g。

4.5标准滴定溶液的浓度以c（A）=mol/L或T（B）/（A）=mg/mL表示，标定其浓度时，应同时

进行三份以上的测定，并进行空白试验比对，所得浓度的相对误差不应大于0.20%，结果取算术平均值

并修约至小数点后四位。

4.6配制、贮存试剂溶液时，对玻璃有腐蚀性的试剂应使用塑料容器贮存，对容易分解的试剂应使用

棕色容器贮存，并标明贮存时的注意事项及贮存时间。

4.7每次试验时，应进行平行空白试验，根据空白试验结果对分析结果进行校正。

4.8应按照GB/T4676对试样进行取样和缩分，再用刚玉研钵研细至试样粒径不大于75μm，混合均

匀，装入试样袋，在105℃～110℃的电热干燥箱中烘干1h～2h，取出，放入干燥器中冷却至室温备

用。分析试样质量不应少于20g。
