This review deals with the chemical phase analysis for mineral and metallurgical products from the publications in China from 1982 to midof 1986, covering three aspects: monograph and conference, chemical phase analysis for elements and others. This paper comments mainly the present state of chemical phase analysis for thirty-one elements.

本文综述了在1982年至1986年国内矿石及冶金产品的化学物相分析发展概况。综述包括专著与会议、各元素的化学物相分析以及其它。主要评述了铝、银等31个元素的化学物相分析方法近几年的发展状况。

The colour reaction of Ga(Ⅲ) with 5-Br-DMPAP has been studied in acidic solution. The apparent molar absorptivity is 1.15×10~5l·mol~(-1)· cm~(-1) at 560 nm. The molar ratio of Ga(Ⅲ) to 5-Br- DMPAP is estimated to be 1:2. Cation interference can be eliminated by extractive chromatography with n-butyl acetate from 6M HCl medium in the presence of TiCl_3 solution as a reducing agent. This method has been applied to the determination of micro amount of gallium in certain metallurgical products with satisfactory...

Sampling inspection plans in the National Standards (GB) and the Ministerial Stan-dards(YB) for steel blooms. rolled products. non-ferrous products. refractory products and car-bon products have been widely and carefully investigated by the use of authour's operationcharacteristic curves ("OC" curves) for metallurgical products. The results show that samplinginspection plans are effective for inspection of metallurgical products. But some plans are not sogood because they do not obey the basic sampling principle or do not work well. Hcnec, thosemethods should be given up to avoid economic loss. On the basis of this investigation, the au-ther suggests to draft a basic standard of sampling inspection plans of metallurgical productsin order that each product can get its right sampling inspection plans.

用笔者给出的求算冶金产品抽样检验方案特性曲线(OC曲线)的方法,对我国的钢坯、钢材、有色金属材、耐火制品和炭素制品的国标(GB)、冶标(YB)中采用的抽样检验方案特性进行了认真细致地研究。发现其中某些方案是适用于冶金产品检验的,也有的方案违背抽样检验的基本原则,有的抽样方法的检验特性不好。后两者都会造成经济损失,应予废止。为保证各种产品采用合理的抽检方案,建议制定冶金产品抽样检验方案的基础标准。
