“…Among the biomaterials, Hydroxyapatite (HAp), a bio-active ceramic, is a ceramic composed of a compound composed of Ca and P as its main component. Biomaterials existing in the body have two characteristics: biofunctionality, which is a property that must be able to perform the desired function perfectly, and biocompatibility, which is a property of a material that is compatible with living tissues [3,4]. However, despite these biocompatible properties, Hydroxyapatite is not widely used.…”

The humidifier vibrator housing is difficult to clean and prone to contamination due to its metallic material. To overcome these shortcomings, the humidifier vibrator housing was manufactured using Hydroxyapatite as a raw material. Although hydroxyapatite has excellent antibacterial properties and biocompatibility, it is difficult to manufacture a sintered body due to its weak fracture toughness. Therefore, hydroxyapatite sintered compacts were prepared according to the amount of plasticizer added and their physical properties were compared. The average compressive strength was 395.1 N·mm-2 at 8 % of the amount of added plasticizer, and the average bending strength was 61.8 N·mm-2 at 6 % of the amount of added plasticizer. The hydroxyapatite sintered compact showed the effect of inhibiting the production of bacteria regardless of the amount of plasticizer added. As a result of this physical property study, it was possible to develop a humidifier vibrator housing with excellent antibacterial properties and maintaining mechanical strength.
