| description | The invention relates to the technical field of materials, in particular to gold powder for LTCC (low temperature co-fired ceramic), a preparation method and gold conductor paste, and the preparation method comprises the following steps: in a water bath environment, reducing chloroauric acid under the conditions of mechanical stirring and ultrasonic vibration by taking D-erythorbic acid as a reducing agent to obtain a reaction solution; centrifuging the obtained reaction liquid, and taking a precipitate; and washing and drying the precipitate to obtain the gold powder. The gold powder prepared through the preparation method is good in dispersity, high in purity and narrow in particle size distribution, after the gold conductor paste prepared from the gold powder as the raw material and an LTCC green tape are co-fired, the structure is compact, bubbles do not exist, a substrate does not crack, the problem that the gold conductor paste and the green tape are not matched in sintering is solved to a great extent, |
