Ceramics play a key role in modern industries such as electronics, aerospace, and energy. Hydrogen, as a clean and highly reactive gas, is essential in several stages of ceramic production. It helps create reducing atmospheres, supports chemical reactions, and ensures the purity and stability of advanced ceramic materials.
1. Application Stages and Functions
(1) Reducing Atmosphere Sintering
In the production of advanced ceramics—such as metal ceramics, carbides, and nitrides—high-temperature sintering must occur in a reducing or oxygen-free atmosphere to prevent oxidation. Hydrogen provides the ideal protective environment due to its strong reducing properties. This ensures the ceramic structure and performance meet high-quality standards.
(2) Reaction Sintering
Hydrogen can also participate directly in chemical reactions. During the preparation of silicon-based ceramics or hydrogen-containing compounds, it reacts with oxygen or other elements in raw materials. This reaction promotes densification and enhances the final strength of the ceramic.
(3) Thin Film Deposition
In advanced coating technologies such as Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD), hydrogen is commonly used as a carrier gas, reactive gas, or cleaning gas. High-purity hydrogen ensures precise control of film thickness, growth rate, and surface quality. As a result, the produced ceramic films achieve superior mechanical and thermal properties.
2. Hydrogen Purity Requirements
High-purity hydrogen is essential for ceramic production. Even trace impurities can alter ceramic microstructures or contaminate material surfaces. Therefore, hydrogen used in sintering and film deposition processes typically requires a purity level above 99.999% (5N), and for ultra-precise applications, it can reach 6N or 7N.
Such levels guarantee stable performance, consistent color, and enhanced durability in the final ceramic product.
