Abstract
"pó de si tendo um tamanho de partícula primário médio entre 20nm,uso do mesmo e ,método de fabricação de um pó de si"um pó á base de si de tamanho submicrônico tendo um tamanho de particula primário médio entre 20nn e 200nn,em que o pó tem uma camada superficial que compreende siox com 0<x<2,sendo quje a camada superficial tem uma espessura média entre0,5 nn e 10nn. e em que o pó tem um teor de oxigênio total igual ou menor que 3% em peso ,em temperatura ambiente.o método para criar o pó compreende uma etapa em que um precurso de si é vaporizado em uma corrente de gás em alta temperatura, após o que a corente de gás e bruscamente resfriada para obter particulas de si,e as partículas de si são bruscamente resfriadas em baixa temperatura em um gás que contém oxigênio.
