MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202417067535 A) filed by Jiangsu New Linzhi Elecronic Technology on September 06, 2024, for Method For Improving Anti-Reduction Performance Of Ptc Thermosensitive Element.
Inventors include Qiuyun Fu Number; Zhengan He; and Dongxiang Zhou.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: Disclosed is a method for improving anti-reduction performance of a PTC thermosensitive element, including coating an inorganic protective layer, organic protective layer, or organic and inorganic composite protective layer coated with a mixture of an inorganic substance and an organic substance for blocking harmful reducing gases from entering an interior of a ceramic body through surface defects or grain boundaries of the ceramic body onto the surface of a PTC thermosensitive element based on barium lead titanate. Advantages: by coating the inorganic protective layer, organic protective layer, or organic and inorganic composite protective layer coated with the mixture of the inorganic substance and the organic substance onto the surface of the PTC thermosensitive element based on barium lead titanate to form an isolation protective layer for blocking reducing harmful gases from entering the interior of the ceramic body through the surface defects or grain boundaries of the ceramic body.
