a transparent plzt ceramic with a composition of the following general formula: $(pb1 - xlax) (zr1 - ytiy) 1 - 0,25xo3 $a (where x is a value of 0.01 to 0.3 and y is a numerical value of 0.05 to 0.95) contains a small amount of samariumoxid or wismutoxid.the process for the production of such a plzt ceramics comprises the steps: manufacture of roasted plzt powder from the oxides of pb, la, zr and ti, or links, by burning in these oxides are transformable.as a raw material; mixing sm2o3 or bi2o3 as sinterhilfsmittel with baked powder, forming the mixture into a shaped product with the desired shape of the molded product; and then undergo the normaldruckbrennen at a temperature in the range of 1000 bi it 1300u00b0c og gas is in a steam containing atmosphere and pb.the procedure can easily be executed and makes it possible to easily sinterfu00e4higes calcined plzt powder from a cheap raw material to produce a dry.the easy sinterfu00e4hige candy plzt powder can be a transparent plzt ceramics with high transparency in good reproducibility, supplying it to a molded product with the desired shape and the molded product is then deformed to the normaldruckbrennen).
