Silicon nitride pellets are a type of vapor deposition material with stable structure, low coefficient of thermal expansion, and excellent oxidation and corrosion resistance. They are widely used in high-tech structural ceramics, various wear-resistant materials, and refractory materials.
Our company (VIMATERIAL) produces silicon nitride sheets with high purity, high nitrogen content, and high sintering activity. We also supply silicon nitride powder and silicon nitride targets. Please contact us if you have any needs.

Optical Coatings: Silicon nitride is used as a high-index layer to reduce reflection and improve surface durability in optical films.
Semiconductor Devices: It serves as an insulating and passivation layer that protects circuits from moisture, contamination, and electrical leakage.
OLED / Photovoltaic Encapsulation: Silicon nitride films act as strong moisture-oxygen barriers to extend the lifetime of OLED displays and solar cells.
Hard Protective Coatings: Its high hardness and wear resistance make it suitable for protective layers on cutting tools, molds, and mechanical parts.
Silicon nitride tablets/granules should be stored in a sealed container in a dry, cool environment. Avoid prolonged exposure to air to prevent moisture buildup, which can affect their dispersion properties and performance.
Furthermore, avoid heavy pressure and contact with oxidants, and transport them as general cargo.

VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
