Ceramic Slurry Composition

A ceramic slurry composition has a powdered ceramic uniformly dispersed therein without excessive damage thereto.

Ceramic slurry composition.

They withstand chemical erosion that occurs in other materials subjected to acidic or caustic environments. The slurry was mixed properly with. A method for producing a ceramic green sheet using the ceramic slurry composition and a method for producing multilayer ceramic electronic devices are also disclosed. It is important to optimize the slurry composition in order to obtain high green density low green shrinkage and sufficient green strength to produce defect free demolding.

A ceramic slurry composition has a powdered ceramic uniformly dispersed therein without excessive damage thereto. A ceramic slurry composition according to claim 1 wherein the average particle diameter of the powdered ceramic is about 0 01 to 1 μm. The slurry comprises a binder a gelling agent a first refractory material having a density of ρ 1 and a mean particle size of α 1 and a second refractory material having a density of ρ 2 and a mean particle size of α 2 wherein ρ 1 ρ2 and α 1 α2. A commercial synthetic binder used with slurry.

Some elements such as carbon or silicon may be considered ceramics ceramic materials are brittle hard strong in compression and weak in shearing and tension. A ceramic mould slurry is disclosed for forming moulds and metal castings of improved surface quality. 3 3 development of ceramic slurry the composition of ceramic mold as shown in table 1 for investment casting was determined with 100 zircon for sample 1 50 zircon ad 50 alumina for sample 2 and 70 zircon and 30 fused silica. Dispersant is used to separate.

A composition and method for forming investment casting shells includes using colloidal silica zircon flour and fused silica in a slurry which is applied to a pattern. Additionally the ceramic slurry composition may have stability such that the at least one ceramic particle polymer and or crosslinking. Ceramic slurry is obtained by mixing ceramic powder carrying vehicle binder and dispersant to produce uniformly dispersed ceramic slurry. A method for producing a ceramic green sheet using the ceramic slurry composition and a method for producing multilayer ceramic electronic devices are also disclosed.

A ceramic slurry composition according to claim 2 wherein the anionic dispersing agent has at least one intermolecular carboxyl group maleate group sulfonic group or phosphate group. The ceramic slurry composition contains the powdered ceramic a dispersing agent a binder and a solvent in which. After the shell has solidified the pattern may be melted or otherwise removed. A ceramic material is an inorganic non metallic often crystalline oxide nitride or carbide material.

After the slurry is applied to the pattern it is allowed to partially or completely solidify. The ceramic slurry composition contains the powdered ceramic a dispersing agent a binder and a solvent in which.
