Glass powder and method of manufacturing the same

Abstract

Provided are a glass powder represented as aLi 2 O-bK 2 O-cBaO-dB 2 O 3 -eSiO 2 wherein a+b+c+d+e=1, and 0.01≦a≦0.1, 0.01≦b≦0.01, 0.01≦c≦0.1, 0.05≦d≦0.3, and 0.3≦e≦0.7 are satisfied in terms of mol %, a method of manufacturing the same, and a multi-layered ceramic material using the same. Therefore, a nano glass powder having an average particle size of 100 nm or less and uniform particle size distribution can be manufactured using liquid phase deposition, specifically, a sol-gel method. In addition, the glass powder can be used as sintering additives to decrease a sintering temperature by about 100° C. in comparison with conventional glass upon manufacture of a ceramic material such as MLCC and MLCI, which can be sintered at a low temperature, contributing to improvement of dielectric capacity and inductance capacity of the parts and increasing quality coefficient.
