Abstract
In a casting method comprising casting a slip containing water or an organic solvent as the medium into a mold and removing the mold after solidification of the slip, use of a mold formed with an organic binder soluble in the medium of the slip allows the slip to quickly solidify and afford a green body due to absorption of the medium in the slip by the mold. In this case, the mold softens with loss of the binding power thereof simultaneously with the absorption of the medium. Therefore, no cracks appear at all in the green body, and removal of the mold is very easy.
Claims16
A slip casting method, comprising casting a slip containing an organic solvent as a medium of said slip into a mold and removing said mold after solidification of said slip, wherein said mold is formed with an organic binder and an aggregate, said organic binder is soluble in said organic solvent, and said aggregate is particles insoluble in said organic solvent.
A slip casting method comprising casting a slip containing an organic solvent as a medium of said slip into a mold and removing said mold after solidification of said slip, wherein said mold is formed with an organic binder and an aggregate, said organic binder is soluble in said organic solvent, and said aggregate is particles insoluble in said organic solvent, and wherein an admixture solvent for said binder is an alcohol, ester, or aromatic solvent, or a mixture thereof.
A slip casting method, comprising casting a slip containing an organic solvent as a medium of said slip into a mold and removing said mold after solidification of said slip, wherein said mold is formed with an organic binder and an aggregate, said organic binder is soluble in said organic solvent, and said aggregate is particles insoluble in said organic solvent, and wherein an admixture solvent for said binder is at least one material selected from the group consisting of trichloroethane, trichloroethylene, methyl alcohol, ethyl aocohol, ethyl acetate, acetone, methyl ethyl ketone, diethyl ether, tetrahydrofuran, hexane, heptane, benzene, toluene, xylene, chloroform, and carbon tetrachloride.
