Hunan Huawei is one of the drafting units of the industry standard YS/T 424-2022 "Chemical Analysis Method of Titanium Diboride Powder". Peng Zhiming, general manager of the company, is one of the main drafters. The standard has been officially implemented on April 1, 2023.The revised standard was proposed and managed by the National Nonferrous Metals Standardization Technical Committee (SAC/TC243). In addition to our company, the main drafting units include Central South University, Changsha Mining and Metallurgy, National Standard (Beijing) Inspection and Certification and other units.

YS/T 424-2022 "Methods for Chemical Analysis of Titanium Diboride Powder" has released the following 5 parts:

Part 1: Determination of titanium content: ferric ammonium sulfate titration method;

Part 2: Determination of total boron content: neutralization titration method;

Part 3：Determination of iron content: 1,10-phenanthroline spectrophotometric method;

Part 4: Determination of carbon content: high-frequency combustion infrared absorption method;

Part 5: Determination of oxygen content: pulse heating inert gas fusion-infrared absorption method.

The titanium diboride powder produced by our company can be applied to hot-pressed ceramic products that require good electrical conductivity, cathode coating materials for industrial aluminum electrolytic cells, hot-pressed titanium diboride + boron carbide composite bulletproof ceramic inserts, diboride Titanium-based cermet materials, battery cathode materials, etc.
