During nonisothermal sintering from 850 to 1 100 ℃,the growing mechanism of fluoramphibole crystals was investigated through the measurement of crystallinity,mean diameter,diameter distribution and number of fluoramphibole crystals using X-ray diffraction and scanning electron microscopy.The results show that an interaction between fluormica and glass occurs during the nonisothermal sintering process,and the fluoramphibole crystals are precipitated by an interaction between the fluormica crystals and glass ...
