Abstract

PURPOSE:To obtain an insulation base plate excellent in productivity by adopting such base plate whose chemical analysis value is MgO 60-90%, Al2O3 8-30%, TiO2 0.01-10% in weight % thereby improving the hydration, strength and degree of sintering without any damage in the excellent heat conductivity and electric insulation of magnesia porcelain. CONSTITUTION:To produce insulation ceramic whose desirable composition area is set as MgO 75-82%, Al2O3 18-22%, TiO2 0.05-3%, MgO powder is produced at first by calcinating Mg (OH)2, then it is mixed with Al2O3 and TiO2 powder to have a desired composition. Next, the mixture is mixed in a wet manner in alcohol, and dried. Then it is press-formed in a fixed form under pressure. Further, it is baked under a fixed condition so that an insulation ceramic is obtained. It can be considered that an effect of Al2O3 restrains growth of MgO crystal particles, improves the strength of sintered body and waterproof performance, and further improves thermal shock resistance owing to low thermal swelling, while an effect of addition of TiO2 improves degree of sintering and waterproof performance of ceramic.
