Synthesis of hydroxyapatite from Snail shell and experimentation on Mechanical behaviour of hap Reinforced bio polymer composites For bone grafting

Abstract

Recent research has identified Nano biocomposites as an effective technique for improving morphological and functional characteristics of synthetic bone transplants. Bioactive ceramics have garnered considerable interest due to their biocompatibility. Nano hydroxyapatite (nHAp) can be the most suitable substitute for bone auxiliary, since it is the mineral component of bone matrix that most closely mimics the bone. The intrinsic low fracture toughness of nHAp supports its usage as a long bone replacement and loadbearing structure. As a result, it is vital to produce composite constituents with enhanced biomechanical properties. The objective of this research is to generate Nano hydroxyapatite nHAp composites using laboratory chemicals and from natural sources such as snail shells. In this endeavor, the synthesis of Nano particle of HAp powder by the sol gel is reported. This method incorporates a chemical mixture which is matured for four days at 80°C using a stirring motion. It is possible to synthesize the nHAp after 12-hour calcination at 600°C. The synthesize of nHAp from the snail shell is done using thermo mechanical process. Snail cell particles are treated at temperatures at 800°C, 900°C and 1000°C in order to remove the protein content and other contaminants. Mole ratio is 4:3 between the snail shell and the dicalcium phosphate dehydrate (DCPD) powder. The slurry is wet milled for 4 hours at 150 rpm in a zirconia container and then, it is dried at 100°C in a convection oven for 24 hours Afterwards, the dry powder is heated in a muffle furnace at a rate of ten degrees Celsius every minute at temperatures of 800°C, 900°C and 1000°C to produce Nano crystalline hydroxyapatite (nHAp). newline
