Abstract
This invention provides alkali metal bicarbonate powder consisting of a narrow size distribution range of ultrafine particles. The ultrafine powder has a large surface area, and provides enhanced reactivity in applications such as deodorization or neutralization, and exhibits increased antibacterial/antifungal activity. The ultrafine powder also has an exceptional capability to form a homogenous solid-phase suspension in a liquid medium which has long term stability.
