“…This study focused on the use of eggshells as implant material and from this study, the best eggshells were duck eggshells with a milling time variation of 5 hours. From the simulation results in the previous research, CaCO 3 from eggshell powder was increase the strength of mastication 40 times and the most important parameter is the crystallite size of CaCO 3 [7,8]. Other application that related to the implant material is hydroxyapatite (HA) that can be obtain from CaCO 3 and natrium phosphate.…”

“…The results of data analysis showed that the crystallite size with a longer milling time had a smaller size. Meanwhile, larger crystallite sizes can be due to agglomeration and also the sintering process which can cause larger grain sizes [7]. This is because at the same time, the grain size increases as the temperature increases, it approaching 1 µm at 1000 °C (1273 K) [27].…”

“…Especially in Indonesia, that has abundant eggshell wastes. This is because the amount of egg consumption by the Indonesian people is quite high, besides that the shell waste is also produced from the remnants of the hatchery in the chicken nursery industry [7]. Another reason is because the egg production in Indonesia increases each year, for example, the production of quail egg in 2013 was 18,936 tons then increases to 25,272 tons in 2017 [8].…”

“…The eggshell also used as filler and precursor for cement mortar in making of gypsum, even used as drug delivery in medical sector [10,11]. For other applications, eggshells also used as reinforcement at cast metal alloy, even used as basic material to make hydroxyapatite which can be used as an implant material for bone and used as tooth filler [7,12,13]. In the form of CaCO 3 , many application has been discussed.…”

Eggshell is bioceramic material that produces by avian that commonly contains of 94 % calcium carbonate, 1 % magnesium carbonate, 1 % calcium phosphate, and 4 % other organic element. This study proposed to investigate the synthesis and characterization of avian eggshell powders. The avian eggshell that used in this study involved chicken, duck, and quail eggshells. The characterization of avian eggshell nanopowder for reducing their grain size from micro to nano involved ball milling process (solid state reaction) with the variation of milling times (3, 5, and 7 hours) and sintering temperature at 1000 oC for 2 hours. X-Ray Diffraction (XRD) test presented the phase characterization of quail eggshell nanopowder which ball-milled for 7 hours, obtained the smallest crystallite size at 19.2 nm. Scanning Electron Microscopy (SEM) test presented the morphological analysis that showed changes in grain size and shape of each variety of the avian eggshell such as spherical, oval, wormlike, cubical, triangular, and some irregular grains. Energy Dispersive X-Ray (EDX) test presented the compound in avian eggshell powders that showed Ca and O level were the highest, while C was the lowest level. Fourier Transform Infrared (FTIR) test presented the possibility of the functional group of the avian eggshell powders that showed Ca-O, Ca=O groups, CaCO3, asymmetric C-O, -CO3, amide, C=O, -OH, alkyl CH, and C-H. While compressibility shown the increase along with the decrease of crystallite and particles size in cubical grain. The highest compression ratio is 67.75 % for chicken eggshell nano powder with 5 hours milling time at 2000 kgf of compression loading
