[Data] Structural Evaluation of Niobium Hydroxide and Niobium Carbide (Reference Catalyst)

This is a document evaluating the structure of niobium hydroxide and niobium carbide (reference catalysts) using gas adsorption methods (specific surface area, pore distribution) and He gas replacement methods (true density assessment).

This document introduces the structural evaluation of niobium hydroxide and niobium carbide (reference catalysts) using gas adsorption methods (specific surface area, pore distribution) and He gas replacement methods (true density evaluation). Niobium hydroxide, which is expected to be utilized in optical lenses, electronic materials (piezoelectric elements, capacitors, SAW filters), acid catalysts, and catalyst supports; reference catalyst JRC-NBO-4, and niobium carbide; reference catalyst JRC-NBO-5-C, were subjected to nitrogen adsorption-desorption isotherm measurements and true density measurements using the He gas replacement method. Structural evaluations were conducted based on the specific surface area, external surface area, pore volume, and pore size distribution of each sample. 【Contents】 ■ Overview ■ Measurement Samples and Evaluation Equipment ■ Measurement Results ■ Discussion *For more details, please refer to the PDF document or feel free to contact us.
