Corrosion-resistant coated laminate

A composition for ceramic dielectrics comprising BaO, CeO2, ZrO2, CaO and TiO2 in sintered state. The composition can also contain at least one of MnO2, Cr2O3, FeO, NiO, and CoO as additive. As the composition is very fine in grain size, and has a prolonged life, it is very suitable for a raw material of such a product as a layer-built capacitor which is used in high electric field.

PROBLEM TO BE SOLVED: To provide a water permeability testing machine by which the water permeability test of a waterproof material can be executed simply without being subjected to the influence of the air. SOLUTION: A testing machine has a structure in which a flange-shaped sample cradle 3 having a water-permeable circular hole is provided in a little upper position from the center inside a hollow cylindrical body 1 at which a water injection port 4 and a compressed-air feed port 5 are formed, a disk- shaped mortar body 15, to be tested, in which a waterproof material layer 14 to be subjected to a water permeability test is formed on one face is faced downward so as to be set on the sample cradle 3 by being sandwiched between a flange-shaped rubber gasket 16 and a flange-shaped rubber gasket 16a and its upper part is screwed so as to be airtight by a lid 11. At this time, the upper part and the lower part of the testing machined are turned over, a water pressure is applied to a water layer formed on the waterproof material layer 14 by compressed air, and a water permeability degree to the waterproof material layer 14 is judged.
