Scandium nitride powder is an advanced ceramic material with high hardness and high thermal conductivity, belonging to the typical rare-earth nitrides. Its unique thermal and electrical properties make it a promising candidate for applications in high-temperature structural components and functional coatings.
We are committed to producing high-purity, low-oxygen-content scandium nitride powder. We can customize products with different particle sizes and crystal forms to meet your application needs. Please feel free to contact us to discuss your specific requirements.
High nitrogen content
Strict oxygen content control
Controllable microstructure, low agglomeration
Stable batch performance, good repeatability
High-performance hard coatings: As a target or precursor for physical vapor deposition, it can form an ultra-hard, wear-resistant protective coating on the surface of cutting tools and molds, significantly extending their service life.
High-temperature structural ceramics: As an additive or main phase, it is used to prepare engine components or thermal protection system materials resistant to extreme temperatures, improving their thermal shock resistance and mechanical strength.
Semiconductor Substrate Materials: Due to its lattice constant matching that of wide-bandgap semiconductors like gallium nitride (GaN), it can serve as a buffer layer or substrate for epitaxial growth, improving the crystal quality of thin films.
Advanced Composite Materials: Introduced as a reinforcing phase into metal or ceramic matrices, it can effectively improve the thermal conductivity, wear resistance, and high-temperature load-bearing capacity of composite materials.
Q1: What is the main phase composition of scandium nitride powder?
A1: Our product is mainly composed of cubic rock salt mineral (ScN) structure. X-ray diffraction (XRD) analysis confirms that the phase purity is typically higher than 95%, and relevant spectra are provided.
Q2: Are there any special requirements for the storage environment of the product?
A2: It is recommended to store it sealed in a dry, inert atmosphere (such as argon) or vacuum, avoiding exposure to humid air to prevent slow hydrolysis or oxidation from affecting its performance.
Q3: How to prevent scandium nitride decomposition during sintering?
A3: Sintering requires a high-pressure nitrogen atmosphere or hot isostatic pressing. We can provide specific sintering process window recommendations based on product characteristics to suppress nitrogen loss at high temperatures.
Q4: Can you provide products with specific particle sizes for coating deposition?
A4: Yes. For processes such as thermal spraying or cold spraying, we can provide optimized powder products with specific particle size distributions and good flowability.
