Production method of forsterite powder, forsterite powder, forsterite sintered body, insulator ceramic composition, and lamination ceramic electronic part

摘要

Being possible to sinter relatively in low temperature, producing the satisfactory forsterite powder of quality economically it becomes possible. Mixing with magnesium source and silicon source and the Cu particle, the Cu particle it produces the mixed powder which is contained in the range 300 - 2000wtppm, calcines this mixed powder. As magnesium source SiO₂ is used Mg (OH) making use of ₂, as a silicon source. Crystalline structure makes the forsterite powder of polycrystals. Mixing with magnesium source and silicon source and the Cu particle, under existing of the solvent, it manufactures the mixed powder. In addition, Cu is made to contain in the ratio 300 - 2000wtppm. Grain size that tries becomes the range of 0.20 - 0.40 millimicrons. In addition, the crystal diameter which forms the forsterite that tries reaches 0.034 - 0.040 millimicrons.
