Electronic materials: Niobium Pentoxide is used in the manufacture of piezoelectric ceramic materials such as lithium niobate, lithium niobate crystals have excellent piezoelectricity, ferroelectricity, photoelectricity, nonlinear optics and other characteristics, it is one of the mainstream opto-electronic materials, it can be used in the manufacture of electronic components, such as filters, resonators and so on, it is widely used in the field of electronics, communications, military and other fields.
Optical field: Niobium Pentoxide can be used in the manufacture of special optical glass to improve the refractive index and optical properties of the glass; it can also be used as an optical coating material for the preparation of high-reflective films, insulating films, filters, etc., which are used in liquid crystal displays, photovoltaic power generation and other industries.
Metallurgical industry: it is an important raw material for the production of various niobium alloys, such as ferro-niobium alloys, special steel, etc., which can improve the alloy’s strength, toughness, corrosion resistance and other properties.
Other aspects: can also be used as a catalyst, refractory materials, etc.
Nb₂O₅ granules can appear either black or white depending on the synthesis process. Factors such as the oxidation/reduction environment, temperature, and type of precursor affect the crystal structure, size, and defect levels. High-purity, fully oxidized granules typically appear white, while particles exposed to partial reduction, impurities, or aggregation during processing may appear black.
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.
