从China供应商批发进口4n 99.99% Niobium Pentoxide Nb2o5 — FOB条款

4N 99.99% Niobium Pentoxide Nb2O5 from Shandong Longtaili Science And Technology Co.,ltd. is a high-purity chemical compound supplied as sinter granules with a size range of 1-3mm or 3-5mm, available upon demand. The product, identified by CAS number 1313-96-8, is white in color and has a density of 4.47 g/cm3, making it suitable for precision applications in optics and coatings.

The material exhibits a refractive index of 2.1 to 2.3 at 550nm, with a transparency range spanning 0.35 to 9 micrometers, which is typical for niobium pentoxide in optical applications. Its melting point is 1530°C, and it is commonly used as an evaporation source in physical vapor deposition processes for high-refractive-index coatings. Standard industry specifications for 4N-grade niobium pentoxide include low impurity levels, critical for applications requiring high optical clarity.

Primary applications include use as a filter material and in high-refractive-index (HR) coatings for lenses, mirrors and other optical components. Buyers in the semiconductor, aerospace and specialty glass industries often source this material for its stability and performance in extreme conditions. Packaging options include 1 kg per bag or can, 2 kg per can, or 20 kg per carton, with storage requiring protection from sunlight, acid exposure and moisture.

Shandong Longtaili Science And Technology Co.,ltd. is located at No.34 Guantao Road, Shibei District, Qingdao City, Shandong Province, China. The company operates within the chemical materials sector, specializing in high-purity compounds such as niobium pentoxide. As a harbor-tier supplier, it is positioned for international trade, though current response metrics indicate a 0.00% response rate with no recorded average response time, suggesting that direct outreach may be necessary for timely communication.

The supplier’s focus on niche chemical products like 4N 99.99% Nb2O5 demonstrates a commitment to serving industries with stringent material requirements. While the profile does not provide additional details on certifications or production capacity, buyers should request comprehensive quality assurance documentation, including purity certificates and traceability reports, to validate the product’s suitability for their applications.
