What is vaporous silica?Vapour silica is one of the most essential high-tech ultrafine inorganic new materials, with porous, non-toxic, tasteless and pollution-free, the average primary particle size of about 7-40 nano, specific surface area of 50 ~ ...…
In many concrete projects, traditional high-efficiency concrete such as the naphthalene series can not meet the needs of engineering and more due to the limitation of technical performance. The new generation of a polycarboxylic acid series high-perf...…
Among the Iron (II) ion Fe 2 + (charge is 2+) and Iron (III) ion Fe 3 + (charge is 3+), the magnitude of positive charge is higher on Iron (III) ion Fe 3 +. Therefore, the size of Iron (III) ion Fe 3 + will be smaller than Iron (II) ion Fe 2 +. Why d...…
