摘要：
The alginate beads encapsulating calcium silicate were prepared. The morphologies and properties of the encapsulated beads were investigated. The beads were prepared by mixing modified calcium silicate with vinyltriethoxysilane in an alginate solution. The alginate-calcium silicate dispersion was dropped into a calcium chloride solution. The mean particle size of the resulting beads depended on the content of modified calcium silicate in alginate solution. In addition, the shape of the alginate gel was controlled by the viscosity of the alginate solution. The result showed that the calcium silicate particles were well dispersed within the matrix of the alginate. The thermal stability of the alginate beads encapsulating the calcium silicate increased with increasing the content of modified calcium silicate.
