GB/T 11069-2017 in English

Background and Significance of Standard Revision

GB/T 11069—2017 High Purity Germanium Dioxide is the latest national standard formulated for high purity germanium dioxide products, replacing the original GB/T 11069—2006 version. The new standard has made a number of technical updates and content revisions on the original basis, mainly involving chemical composition requirements, test methods and quality inspection rules.

With the development of the semiconductor industry, the demand for high purity germanium dioxide continues to increase, and higher requirements are placed on product quality and technical indicators. The revision of this standard aims to meet market demand, enhance product competitiveness, and provide an important basis for standardized production in related industries.

Chemical composition and physical performance requirements

The chemical composition of high-purity germanium dioxide is its core quality indicator, which is mainly reflected in the impurity content and purity level. According to Table 1, the purity of GeO2-06 grade reaches 99.9999%, while that of GeO2-05 grade is 99.999%.

The newly added determination method of volatile matter (Appendix A) adopts the muffle furnace high temperature burning method to ensure the accuracy of the test results. At the same time, the determination of bulk density (Appendix B) is completed by a combination of electronic balance and glass measuring cylinder, and the measurement accuracy reaches 0.1g.

Test methods and quality inspection

The standard stipulates a number of testing indicators, including impurity content, chlorine content, volatile matter, moisture, electrical properties, etc. Among them:

• Impurity content is determined by YS/T 37.2 and YS/T 37.4 methods
• Chlorine content is determined according to YS/T 37.1 standard
• Added Appendix A for volatile matter determination, using muffle furnace high temperature calcination method

Technological evolution and application fields

Compared with the 2006 version, the 2017 version of the standard mainly adds the following contents:

Implementation suggestions and precautions

To ensure the effective implementation of the standard, it is recommended that:

1. Enterprises should be equipped with advanced testing equipment, such as muffle furnaces, analytical balances and glass measuring cylinders.
2. Sampling should be carried out strictly in accordance with the sampling method specified in the standard to avoid deviations in test results due to improper sampling.
3. Strengthen personnel training to ensure that technical personnel are familiar with the revised content and technical requirements of the new standard.
