High physical property ceramic body and manufacturing method thereof

Abstract

To provide a high physical property ceramic which remarkably improves defects such as weakness of low-cost ceramics.SOLUTION: A high physical property ceramic body comprises a sintered body obtained by heating a ceramic industry raw material uniformly including an iron component of 10 wt.% or over at a temperature for sintering, followed by cooling.

Description

[Technical field]

[0001] The present invention relates to a highly physical ceramic body having various excellent physical properties and a method for producing the same. [Background technology]

[0002] Generally, ceramic products are non-flammable and resistant to chemical changes, but they have drawbacks such as lack of thermal and sound insulation and being prone to cracking. Furthermore, ceramic products with high physical properties are extremely time-consuming and expensive to manufacture, and their physical properties are also limited.

[0003] DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0004] An object of the present invention is to solve the above-mentioned problems. [Means for solving the problem]

[0005] Ceramic raw materials containing a uniform iron content of 10 wt % or more are heated to a temperature sufficient for sintering and then cooled, and the resulting sintered body is the high-physical properties ceramic body of the present invention.

[0006] The base ceramic raw material here can be, for example, crushed basalt or volcanic eruptions from Miyakejima, etc. Alternatively, silica or low-cost bakuhanseki stone or the like can be appropriately mixed with iron oxide powder to reach a predetermined content.

[0007] In this case, it is optional to mix in an appropriate amount of a binder such as frit or a foaming agent such as carborundum. Effect of the Invention

[0008] The ceramic body obtained by this invention exhibits amazing physical properties beyond imagination. For example, when a nail is driven into it, it penetrates without cracking or deforming at all, and leaves no residue in its path. It also has higher insulation properties than ordinary foam ceramics or foam glass, and it also has sound absorption and sound insulation properties. The porosity and size of the voids can be selected at will, and those with independent voids are completely waterproof and can even float on water, making it suitable for a wide variety of uses. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Two parts by weight of powdered Maifanseki, a ceramic raw material, are mixed with one part by weight of ferrite powder, also a ceramic raw material, along with a small amount of water glass-based frit, and this is pressed into a plate measuring 20 cm in length and width and 1 cm in thickness. It is then heated for several tens of minutes and cooled to form the basic shape of the product. [Industrial Applicability]

[0010] The effects of the present invention are extremely significant and diverse, the material resources are inexhaustible, there are no harmful substances or pollution, and mass production at low cost is easy, so it can be said that the present invention has sufficient industrial applicability.

Claims
