3) hardystonite
['hɑ:distə,nait]
锌黄长石
1.
The studied results show that feather-like hardystonite crystallizes in R2O-CaO-ZnO-Al2O3-SiO2, systems and the macrocrystalline of it will be gotten in the low concentrations of SiO2 and Al2O3, It is evident that the tendency towards the crystallizing of Hardystonite decreases with the equimolecular substitution of K2O by Na2O when the .
