The present invention relates to a glass composition having a composite composition system in which a borate composition and a silicate composition are mixed, and disclosed are an eco-friendly detergent glass composition and a method for preparing an eco-friendly detergent glass powder by using same, the composition having maximized elution of ions such as K.sup.+, Na.sup.+, Ca.sup.2+ and Mg.sup.2+, thereby enabling high-concentration elution water to be prepared. Therefore, the eco-friendly detergent glass composition and the method for preparing an eco-friendly detergent glass powder by using same, according to the present invention, enable a predetermined amount of glass to be repeatedly used and washing performance to be maintained constant up to at least 40 cycles.

This application provides nanocrystal glass, a preparation method, a nanocrystal glass product, and an electronic device, and belongs to the field of nanocrystal glass preparation technologies. The nanocrystal glass includes the following components in terms of mole percents of oxides: Al.sub.2O.sub.3: 30%-55%; CaO: 25%-55%; an alkaline earth metal oxide: 8%-20%; an alkali metal oxide: 3%-15%; B.sub.2O.sub.3: 0%-10%; and Sb.sub.2O.sub.3: 0%-1%. In the nanocrystal glass in embodiments of this application, alkaline earth metal ions and alkali metal ions are added to a glass system including calcium and aluminum, so that glass-forming performance is effectively improved while relatively high mechanical strength of the nanocrystal glass is maintained, thereby reducing a temperature and energy consumption for glass melting.
