Atmosphere melting and forming method for terbium-activated silicate glass

The invention discloses an atmosphere melting method for terbium-activated silicate glass, which can effectively control the valence state of Tb doped silicate glass to strengthen the luminous intensity, and can solve large-dimension glass high-temperature forming. The atmosphere melting and forming method is achieved by the following technical proposal: arranging a crucible to an induction coil of a melting furnace, adding Tb doped silicate glass ingredient to the crucible with a stay-warm case, turning on a radio-frequency power supply RF1 to heat up the ingredient, turning on a material leakage tube radio frequency heater RF2 after the temperature reaches 1450 DEG C, so that the temperature reaches 1250 DEG C; adding material plugging glass, simultaneously, ventilating compressed air outside the material leakage tube; adding the uniformly mixed glass material, turning on an agitator after the glass is completely molten, simultaneously, ventilating inert protective gas and stopping the agitation aft
