In concepts for new products, the price, performance, and product safety criteria are equally important and have a corresp...
متن کاملTHE EFFECT OF RAW MATERIALS CONCENTRATION ON HYDROXYAPATITE POWDER CHARACTERISTICS AND SINTERING BEHAVLOR
Ultrafine hydroxyapatite (HAp) powders with crystallite size in the range of 10-90 nm were synthesized by chemical precipitation process using Ca(OH)2 and H3PO4 solutions as starting materials. Molar ratio of Ca/P=1.68 was kept constant throughout the process and alkaline condition for the reaction was maintained using ammonium hydroxide. The role of raw material concentration on HAp crystallit...
