1 Scope

GB/T 10118-2023 is the Chinese national standard on high purity gallium, in the field of metallurgy. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 28 December 2023 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2024. Classification: ICS 77.150.99, CCS H66. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, accompanying documents and order orders for high-purity gallium content: This document applies to the production, testing and quality evaluation of high-purity gallium with a purity of not less than 99:9999%:

Note: High-purity gallium is mainly used for the preparation of compound semiconductors, high-purity alloys and doping of semiconductor materials:
