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.

摘要： A process for preparing a triazine-based precursor for producing a micro-particulate complex containing a far infrared-emissive silica particle comprises steps of: a) subjecting 2-4-6-trichloro-1,3,5-triazine and a first nucleophilic compound to a displacement reaction in the presence of a first solvent at a first temperature range to form an intermediate; and b) subjecting the intermediate and a second nucleophilic compound to a further displacement reaction in the presence of a second solvent at a second temperature range higher than the first temperature range.
