Scope

GB/T 47610-2026 is the English-translated version of 氮化铝陶瓷粉体.

GB/T 47610-2026 is the Chinese national standard covering aluminium nitride powder - the feedstock for the substrates that carry power electronics, chosen because it conducts heat almost as well as a metal while insulating electrically, and whose oxygen content is what decides how well the sintered part will do that. It fixes the grades, the particle size and morphology, the oxygen and metallic impurities, and the tests. First edition, in force from 1 December 2026. It was issued on 25 May 2026 and takes effect on 1 December 2026, as a first edition. The document is under the responsibility of the China Building Materials Federation. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

Aluminum nitride ceramic powder

1.Scope This document specifies the grading, requirements, test methods, inspection rules, marking, packaging, transportation and storage of aluminum nitride ceramic powder materials. This document applies to aluminum nitride ceramic powder.

3.Terms and Definitions This document does not contain any terms or definitions that need to be defined.

4.Grading This document classifies aluminum nitride ceramic powder into three grades. Grade I, Grade II, and Grade III, based on powder quality and particle size distribution.

5 Requirements

5.1 Appearance Quality Aluminum nitride ceramic powder is in the form of fine particles, grayish-white in color, and uniform in color.

5.2 Physical Properties The physical property requirements for aluminum nitride ceramic powder are shown in Table 1.

5.3 Chemical composition The chemical composition requirements for aluminum nitride ceramic powder are shown in Table 2.

6 Test Methods

6.1 Test Conditions Unless otherwise specified, all tests are conducted under standard atmospheric conditions, with the following environmental parameters.

---Temperature. 15°C~35°C;

---Relative humidity. 45%~75%;

---Atmospheric pressure. 86kPa~106kPa.

6.2 Appearance The color of aluminum nitride ceramic powder was visually inspected under bright white light.

6.3 Particle size distribution The test shall be conducted according to the method specified in GB/T 19077.

6.4 Specific surface area The test shall be conducted according to the method specified in GB/T 39713.

6.5 Whiteness The test shall be conducted in accordance with the method specified in GB/T 23774.

6.6 Carbon, oxygen, and nitrogen content The test shall be conducted in accordance with the method specified in GB/T 16555.

6.7 Iron, silicon, calcium, and magnesium content The test shall be conducted in accordance with the method specified in GB/T 23942.

6.8 Aluminum content The test shall be conducted in accordance with the method specified in ISO 21814.

7.1 Inspection Classification and Requirements

7.1.1 Inspection is divided into factory inspection and type inspection.

7.1.2 Products may only leave the factory after passing inspection. The factory inspection and type inspection items shall include all items required in Chapter 5.

7.1.3 Type testing shall be conducted under any of the following circumstances.
