摘要:
The present invention provides the first package (10) for brittle sheets, which comprises the brittle sheets (12) which are placed in a state of multiple layers and the end cushioning materials (20) (20) which are larger than the outer shape of the brittle sheets (12) and whose elasticity range from 2 to 100 mm and which are placed at both ends of the brittle sheets of lamination. The present invention also provides the second package for brittle sheets, which comprises the brittle sheets which are placed in a state of multiple layers, and the side cushioning material whose proof compressive load is not less than 1960 N in vertical direction and not less than 98 N in lateral direction and which is placed at the side of the said brittle sheets of lamination.
摘要:
A ceramic sheet has a burr height on the periphery of the sheet of ±100 µm or less and/or a dimple height on the sheet surface of 100 µm or less, as determined by irradiating the sheet with a laser beam to measure reflected light, and three-dimensionally analyzing the reflected light with a laser optical three-dimensional profiling instrument. This sheet is highly resistant to stacking-induced loads and thermal stresses. Further, when the ceramic sheet includes a zirconia ceramic partially stabilized with 2.8 to 4.5% by mole of yttria and containing 0.1 to 2% by mass of at least one dispersed reinforcing oxide, in which the grain size of the surface of the sheet has an average of 0.1 to 0.4 µm, a maximum of 0.4 to 0.8 µm, and a coefficient of variation of 30% or less, which grain size is determined by scanning electron microscopic observation, the ceramic sheet has satisfactory strength at room temperature and at high temperatures and satisfactory durability of strength at high temperatures. The ceramic sheet is very useful as, for example, a solid-electrolyte film of a solid oxide fuel cell.

摘要:
A chelating composition containing an aliphatic polycarboxylic acid of the following formula (I): wherein A is an imino group or an oxygen atom, R is a hydrogen atom or a hydroxyl group, and n is 0 or 1, or the salt thereof and sugar or saccharic acid of 4 to 12 carbon atoms at such a ratio as enables the components to manifest synergistic effects is provided. This chelating composition is capable of effectively sequestering a metal ion and preventing the metal ion from being insolubilized without causing pollution of the environment.
