| titleOfInvention | Pyroelectric porcelain composition |
| abstract | PURPOSE: To obtain a pyroelectric porcelain composition expressed by the specific formula, obtained by incorporating Mn as a subsidiary component into a complex oxide containing Pb, Ca, Cu, W and Ti as main components, being dense and having big mechanical strength, high pyroelectric evaluation index and relatively high Curie temperature. n CONSTITUTION: The aimed pyroelectric porcelain composition constituted by incorporating 0.3W2.5atom% Mn as a subsidiary component into the above- mentioned complex oxide having composition expressed by the formula and used as a main component. The above-mentioned composition is produced by using Pb 3 O 4 , CaCO 3 , CuO, WO 3 , TiO 2 and MnO 2 as raw materials and weighting these materials so as to give a composition shown in the table 1 and blending each blending each raw material in wet state. Then the blend is dried, calcined and powdered and blended with an organic binder in wet state, granulated and then formed into uniform particle. Then the resultant powder is press into desired shape under pressure and burned. Pyroelectric element having high pyroelectric coefficient, 200°C Curie point and high temperature stability and sensitivity as shown in the table 1, ≥ is obtained from the disc like pyroelectric porcelain composition. n COPYRIGHT: (C)1989,JPO&Japio |
