标准摘要
[中文适用范围]: 本文件描述了冶炼级氧化铝的样品制备方法。 它涵盖了将大块样品减少 1 公斤至 20 公斤,以产生适合化学和物理分析的样品。 产生的减少的样品将代表初始批量样品。 批量样品被认为来自一个来源。 该方法适用于干燥、自由流动的氧化铝。 由于水分含量会影响许多物理分析,该方法旨在尽量减少样品与大气的接触,以避免吸水。 [外文原描述]: This document describes methods for the sample preparation of smelter-grade aluminium oxide. It covers the reduction of a bulk sample between 1 kg and 20 kg to produce a sample that is suitable for chemical and physical analysis. The reduced sample produced will be representative of the initial bulk sample. The bulk sample is considered to be from one source. The methods are suitable for dry, free-flowing aluminium oxide. As the moisture content will influence many physical analyses, the method aims to minimize the exposure of the sample to the atmosphere to avoid water absorption.
英文名称Aluminium oxide primarily used for the production of aluminium — Preparation and storage of test samples
