摘要： A piezoelectric ceramic material which can suppress segregation of a W compound or a W oxide in W-containing sintered PbTiO3 and a piezoelectric transducer employing the ceramic material. The ceramic material contains lead titanate as a primary component; an Mn-containing oxide or an Mn-containing compound and a W-containing compound or a W-containing oxide as secondary components; and an Si-containing oxide or an Si-containing compound as an additional component. Alternatively, the piezoelectric ceramic material contains a primary component containing PbTiO3 and Pb(MnyW(1−y))O3 and additionally SiO2 or PbSiO3.

摘要： The disclosed invention relates to PMN compounds, powders and products thereof, especially to PMN-PT compounds, powders and products which have the perovskite structure. The PMN-PT compounds are characterized by the formula (1−x)Pb(Mg1/3Nb2/3)O3−xPbTiO3 where x is about 0.0 to about 0.95, preferably x is about 0.0 to about 0.40. The compounds are made by sintering a precursor powder of the compound. PMN-PT products produced from the precursor powders have much greater densities than products produced from PMN-PT starting powder. The invention also relates to textured PMN-PT produced from the precursor powders.

摘要： A method for injection molding fine particulate ceramic ferroelectric materials to form an article such as ink jet printhead includes the steps of spray drying fine particulate ceramic ferroelectric material to form agglomerate material; mixing the spray dried fine particulate ceramic ferroelectric agglomerate material with a binder system including materials selected from the group consisting of wax having wax components of different molecular weight, magnesium-X silicate, agaroid gel forming material, and agaroid gel forming material mixed with magnesium-X silicate to form a compounded material; injecting the compounded material at a selected pressure into a mold to form a green article; debinding or drying the green article; sintering the debinded or dried green article to form the final molded article; poling the final molded article to align the electrical dipoles within the piezoelectric material; forming a coating of conductive material over the top and bottom surfaces of the final molded article and then cutting grooves through conductive coating into the top surface in the valleys of the final molded article to form a channel member; and providing an orifice plate over top surface of the channel member and a substrate over the bottom surface of the channel member.
