High-temperature stable ceramic powder and preparation method of ceramic substrate thereof
The invention discloses high-temperature stable ceramic powder and a preparation method of a ceramic substrate thereof, and belongs to the field of electronic components. The ceramic powder comprises calcium carbonate, strontium carbonate, zirconium dioxide, niobium pentoxide and zinc oxide; strontium carbonate, zirconium dioxide and titanium dioxide are adopted to synthesize a zirconium-strontium-calcium-titanium main body material; niobium pentoxide, zinc oxide and calcium carbonate are adopted to perform doping modification on a zirconium-strontium-calcium-titanium main body material to form zirconium-strontium-calcium-titanium-based ceramic powder, namely the high-temperature stable ceramic powder. The preparation method of the ceramic substrate comprises the following steps: (1) adding a dispersing agent, a solvent and a binder into the zirconium-strontium-calcium-titanium-based ceramic powder; (2) preparing tape casting slurry through a ball milling process; and (3) carrying out tape casting, piece cutting, lamination, isostatic pressing, hot cutting, glue discharging and sintering on the tape casting slurry to obtain the ceramic substrate. The problems of low dielectric constant, high sintering temperature and poor temperature characteristic of existing calcium zirconate serving as a ceramic main body material are solved. The preparation method is widely applied to the fields of high-temperature stable ceramic powder and ceramic substrates thereof.
