Method of manufacturing a microwave band dielectric material having high quality factor and excellent temperature characteristics

摘要

The present invention has a quality factor (Q) of 4500 to 5500 in a high frequency band (9 to 11 GHz) and a temperature coefficient ( _f) Is-6 to 17 ppm /C, and to a dielectric material made by such a method.;The method of the present invention comprises preparing a Ba-Ti-citrate aqueous solution by crushing a citric acid aqueous solution into a mixed solution of a compound of barium (Ba) and titanium (Ti), and adjusting the pH of the aqueous solution of Ba-Gelling, drying, and heat treatment of the dried dielectric material.
