Claim:
1. A preparation method for a low temperature co-fired ceramic powder, the preparation method comprising the steps of: 1) weighing R 2) presintering the raw material powder in a muffle furnace followed by grinding to give the low temperature co-fired ceramic powder, the presintering comprising gradiently heating the raw material powder to a maximum temperature of not higher than 950° C., during which a furnace temperature first rises to 350-450° C. and stays thereat for a period, then, as the temperature rises, stays at each interval of 50-100° C. thereabove for a period, wherein the low temperature co-fired ceramic powder has the chemical composition of xR the low temperature co-fired ceramic powder is a low softening point multi-component crystalline phase material having a melting point lower than 850° C.
