摘要

the present invention relates to a process for the manufacture, packaging and stabilization of a family of additives based on sodium, potassium, boron, silicon, zinc and calcium oxides, among others, prepared using physical methods -chemical and chemical synthesis, which forms manometric structures, and which is reformulated with deflocculating, sequestering and dispersing additives that allow to obtain a dispersion or powder capable of decreasing the sintering temperature of a ceramic body due to its high melting power, which is maximized with the use of nanotechnology in the structures obtained. the process consists of the preparation of nucleation seeds of metal oxides, silicates and carbonates, which allow, through a chemical process, to develop nanometric structures in a process of chemical synthesis in wet process of oxides of sodium, boron, silicon, zinc, potassium and calcium.
