PURPOSE:To improve mechanical strength of low-temperature sintering porcelain composition without damaging physical properties, by blending a main component containing codierite, B2O3 and one or more of CaO, SrO and BaO in specific ratio with silver. CONSTITUTION:A main component consisting of (A) 60-90wt.% codierite, (B) 5-20wt.% B2O3 and (C) 1-25wt.% one or more of CaO, SrO and BaO is blended with 0.01-5wt.% calculated as Ag of Ag or Ag-containing compound (e.g., AgO,. AgCl, AgBr or AgNO3) to give a low-temperature sintering composition for multi-layer base suitable as a multi-layer porcelain base having formed a circuit between porclelains. |
