摘要:
The present invention relates to a silicon dioxide composite particle with far-infrared radioactivity, which is formed by the hydrolysis, condensation and polymerization of an organic silane precursor having the structure of the formula (I) with a tetra-alkoxysilane. The high stability of organic silane precursor compounds and the low biotoxicity of silicon dioxide composite particles make the present far-infrared radioactive silicon dioxide composite particles of great potential for extensive use in related bio-products.
