PURPOSE:To shorten the dewaxing time by narrowing the individual boiling points of the components in a specific range, respectively. CONSTITUTION:The organic binder for forming ceramics contains a wetting agent, a lubricant and a binder, individually boiling at lower than 100 deg.C. The binder is mixed with a ceramic powder, the mixture is compressed with heat to give a formed product. The formed product is dewaxed to remove the binder, and calcined to give a sintered ceramic. At this time, binder not containing organic substances boiling at a temperature other than, for example, 200 to 300 deg.C. Thus, the binder in the formed product is removed by raising the temperature gradually in the range of the boiling points and rapidly in the other temperature range whereby the dewaxing time can be shortened. |
