The invention discloses low-melting-point glass powder which adopts (Bio)2CO3, B2O3 and ZnCO3 material systems. The glass powder with nano-sized particle size is obtained by using a vacuum ball grinding method, the sealing temperature of glass powder slurry is effectively reduced, and the material utilization rate and the conversion rate are high. The invention also provides the glass powder slurry and a preparation method thereof. 本发明公开了低熔点玻璃粉，采用(BiO)CO、BO和ZnCO的材料体系，利用真空球磨法获得粒径为纳米级的玻璃粉，有效降低玻璃粉浆料的封接温度，且材料利用率及转化率高。本发明还提供种玻璃粉浆料及其制备方法。
