Preparation and Modification of Low Melting Glass as High Temperature Oxidation-resistant Coatings Binder for Steel Ingots
|
Abstract:
The low melting glass used as a binder for high-temperature plain carbon steel was synthesized by P2O5,ZnO,and Na2O,then modified with B2O3,Fe2O3,MnO,CoO,and NiO.The results of DTA and XRD showed that the low-melting glasses could be changed to glass-ceramic with heat treatment.Zinc phosphate was precipitated from the A glass which modified with B2O3 and Fe2O3 after the heat treatment,while nickel phosphate was precipitated from the glass C which modified with B2O3,Fe2O3,MnO,CoO and NiO.The softening temper...
