| Abstract: | The effect of ZnO/Na2O molar ratio(Z)on the properties of Li2O-K2O-SiO2-Al2O3-B2O3 system vitrified bonds and cBN grinding wheels were studied with TG-DSC,X-ray diffraction analysis,scanning electron microscopy and thermal expansion coefficient tests.The results showed that the lower inflation crystalline phase(Li2OAl2O37.5SiO2)appeared in the vitrified bond.And by increasing the ratio of Z,all the vitrified bonds' topographic crystal temperature,softening temperature,crystal quantity and density increased ... |
