摘要： PURPOSE:To improve porosity and battery performance by producing LiAlO2 through reaction of Al2O3 and lithium salt which is caused on a sintered electrolytic base plate form comprising gamma-LiAlO2 power, Al2O3 and lithium salt power. CONSTITUTION:An matrix materials of an electrolytic base plate, gamma-LiAlO2 powder added to a mixture of Al2O3 powder and lithium salt is fired forming an electrolytic base plate. Al2O3 and lithium salt reacts producing LiAlO2. Pores are formed at places where lithium salt has been present in the base plate. The porosity of 60-65% and the dimensional change in the firing process is small. By setting the mole ratio of added lithium salt and Al2O3 at 0.7-1.2 and the Al2O3/gamma-LiAlO2 weight ratio at 10-30, the pore diameter and porosity are maintained. By the arrangement, performance of the battery can be improved.

摘要： PURPOSE:To provide a non-lubrication type piston having a superior heat resistance, by forming ring-like grooves on an outer circumferential surface of an engine piston of ceramic sintered materials to be contacted with a cylinder liner and thereby eliminating provision of a piston ring. CONSTITUTION:In an engine piston 1 formed of ceramic sintered materials, ring- like grooves are formed on an outer circumferential surface of the piston 1 to be contacted with a cylinder liner 2. The grooves are formed, for example, to be a stepped shape as a whole. Such a shape of the grooves may be designed to a suitable sectional shape according to engine output, piston diameter, compression ratio and workability of ceramics. With this structure, no piston ring is required, and reduction of air tightness is suppressed by a labyrinth effect as exhibited by the grooves. Accordingly, it is possible to obtain a non-lubrication type engine piston having a superior wear resistance and heat resistance.
