Title: The Innovations of Chau-Ting Chang
Introduction
Chau-Ting Chang is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of superconductors, holding a total of 3 patents. His work focuses on innovative processes for creating high-temperature superconducting materials.
Latest Patents
Chang's latest patents include a precipitation process for forming Bi-Pb-Sr-Ca-Cu-O superconductors. This process involves preparing a powder of high-temperature oxide superconductors of the Bi-Pb-Sr-Ca-Cu-O type. In an aqueous solution of nitrate salts of Bi, Pb, Sr, Ca, and Cu metals, an appropriate ratio of triethylamine and oxalic acid is added to form a coprecipitate. The process includes calcination at temperatures ranging from 750°C to 800°C and sintering at 860°C, resulting in a uniform and fine powder superconductive metal oxide with a critical temperature of 110K.
Another notable patent is the homogeneous coprecipitation method for preparing YBaCuO superconducting materials. This oxalate route coprecipitation process involves preparing an aqueous solution of nitrates of yttrium, barium, and copper, which is mixed with an organic solution containing a dibasic oxalate ester, an organic base, and acetone. Ultrasound vibration is applied to the mixture to coprecipitate oxalates of yttrium, barium, and copper. This method enhances the decomposition of the oxalate ester and ensures fine and uniform particle size.
