Title: Chung-Kwang Chiang and His Work on High-Purity Tl-Based Superconductors.
Introduction
Chung-Kwang Chiang is an inventor associated with Taipei, Taiwan, and the Industrial Technology Research Institute. His listed patent concerns a preparation method for a high-purity thallium-based superconductor with a transition temperature of 115 K.
Latest Patents
Chiang is credited with 1 patent: “Preparation Method of High Purity 115 K Tl-Based Superconductor.” The invention describes preparing a precursor with the composition (TlₐPbᵦBi꜀)Sr₂₋ₓCa₂₊ₓCuᵧO𝓏, where a + b + c = 1, 0 < x ≤ 1, and 2 ≤ y ≤ 4. The method uses oxalic acid as a chelating agent, in an amount equal to half the total molar quantity of nitrate anions in the metal-nitrate solution, and adjusts the solution’s pH to produce the superconductor.
