Abstract
The present disclosure relates to a vaporization unit of a microparticle generator, and more particularly, to a vaporization unit of a microparticle generator in which a material having a small difference in heat transfer rate from a heating coil holds liquid, thereby preventing carbonization. A porous ceramic heater includes a porous ceramic prepared by mixing a silicate, a binder, and a pore-forming agent to form a slurry and then performing molding, drying, and sintering thereon and a resistance heating element coupled to the porous ceramic, generating heat when current is applied to heat the porous ceramic, wherein liquid supported on the porous ceramic is vaporized by heat of the resistance heating element.

1-39. (canceled)
A porous ceramic heater, comprising:
- a porous ceramic prepared by mixing a silicate, a binder, and a pore-forming agent to form a slurry and then performing molding, drying, and sintering thereon, wherein SiO2 is added to the porous ceramic, and the silicate constituting the porous ceramic is magnesium silicate or aluminum silicate, and the silicate constituting the porous ceramic is spherical particles, and wherein the porous ceramic has a shape of a hexahedron, a cylinder, or a bath;
- and
- a resistance heating element coupled to the porous ceramic and configured to generate heat when current is applied to heat the porous ceramic, wherein the resistance heating element has a width of 0.05 mm or more and wherein a minimum thickness of the porous ceramic is 0.5 mm or more,
- wherein liquid supported on the porous ceramic is vaporized by heat of the resistance heating element.
