According to the present invention, an additively manufactured ceramic core having both strength and collapsibility, and meltability and moreover having surface roughness improved is provided. The additively manufactured ceramic core disclosed herein is an additively manufactured ceramic core to be used as a core when manufacturing a metal casting and includes a central part corresponding to an additively manufactured fired body of a predetermined ceramic powder, a first layer covering at least a part of the central part, and a second layer formed on a surface layer of the first layer. When an average erosion rate corresponding to an average value of erosion rates calculated from an expression: erosion rate (μm/g)=B/A in which A g represents a projection quantity of projection particles and B μm represents an erosion depth in a fragility test is used, the average erosion rate of the first layer is lower than that of the central part and the average erosion rate of the second layer is higher than that of the first layer. The second layer has a surface roughness Ra of 10 μm or less.

Additively manufactured ceramic core and manufacturing method for the ceramic core

A non-combustion suction device includes: a mouthpiece having a suction port; a container configured to accommodate an aerosol source; and a heater including: a porous ceramic substrate that permits infiltration of the aerosol source; a glass layer at least in part on the porous ceramic substrate; a pair of electrode patterns; and a resistor pattern on the glass substrate, the resistor pattern connects the pair of electrode patterns to each other; and a power source connected to the pair of electrode patterns. The power source is configured to supply a power flow through the pair of electrode patterns to cause the resistor pattern to generate heat which atomize, into an aerosol, the aerosol source infiltrated in the porous ceramic substrate; and the porous ceramic substrate has a ratio of porosity to tortuosity of 21 or more.

A ceramic porous body has an alumina porous body made up by binding aggregate alumina particles to each other, the aggregate alumina particles being bound to each other by a compound including gadolinium silicate, lanthanum silicate or yttrium silicate synthesized from a silicate mineral and at least one rare-earth oxide selected from GdO, LaO, and YO, and an inorganic porous film formed on the alumina porous body.

A hazardous substance treatment agent has a retainer and a transition metal oxide. The retainer has the specificity of retaining only a specific hazardous substance, such as a virus, a bacterium or a toxin, that has become mixed in or has the possibility of becoming mixed in a treatment subject, such as blood, that is in at least either a liquid or gaseous phase. By a photocatalytic action, the transition metal oxide inactivates said hazardous substance retained by the retainer.
