Bioactive borate glass scaffold for bone tissue engineering

Borate glass particles and microspheres with size distributions in the range of approximately 100–400 μm, were loosely compacted and sintered for 10 min at 600 °C to form a porous, three-dimensional construct (porosity 25–40%). Conversion of the borate glass to hydroxyapatite was investigated by soaking the constructs in a solution of K2HPO4 (0.25 M) at 37 °C and with a pH value of 9.0, and measuring the weight loss of the constructs as a...
