Ceramic sintered body, ceramic substrate, mounting substrate, electronic device, and method for producing ceramic sintered body
The sintered ceramic body contains Al2O3 (alumina) and an additive, and the content of Al2O3 is 94% by mass or more. The additive contains SiO2 (silicon dioxide), CaO (calcium oxide), MgO (magnesium oxide), TiO2 (titanium oxide) and Fe2O3 (iron oxide). The content of Ti (titanium) in the ceramic sintered body is 120 ppm or more in terms of TiO2, and the content of Fe (iron) in the ceramic sintered body is 180 ppm or more in terms of Fe2O3.
陶瓷烧结体，由含有Al2O3(氧化铝)和添加剂，Al2O3的含量为94质量％以上的陶瓷烧结体形成。添加剂中含有SiO2(二氧化硅)、CaO(氧化钙)、MgO(氧化镁)、TiO2(氧化钛)和Fe2O3(氧化铁)。陶瓷烧结体中的Ti(钛)以TiO2换算的含量为120ppm以上，并且，Fe(铁)以Fe2O3换算的含量为180ppm以上。
