Abstract
Provided are glass compositions uniquely applicable for the preparation of ultrafine fibers for filtration and separation applications. The glasses meet all physical and chemical criteria, including that for biodissolution rate. In particular, the glasses exhibit good moisture resistance in combination with excellent biosolubility, allowing for storage of products under humid conditions and degradation at a high rate in the body if inhaled.
