Resumen:
beta-Tricalcium phosphate (beta-TCP) is one of the most investigated
calcium phosphates to be used in bone tissue regeneration. Nowadays,
beta-TCP has been synthetized by different methods that allow obtaining
different morphologies with chemical compositions similar to the bone
tissue, broadening the possibilities of use. In this work, beta-TCP
powders were obtained using two different routes: mechanosynthesis and
sol-gel. Results shown that both methods had significant effects on
morphology and size particle of the obtained powders. The average size
particles obtained using mechanosynthesis at 24 and 12 h of milling time
were 1000 and 170 nm, respectively. The average size particles of the
powders fabricated using sol-gel was 350 nm, and the average powder
particle size of the sigma reagent was 1450 nm. Besides, sol-gel and
sigma reagent powders were observed residual phases, instead
mechanosynthesis shown only tricalcium phosphate beta phase. The
formation of agglomerates with different sizes was observed in both
methods by sol-gel and mechanosynthesis. (C) 2018 SECV. Published by
