INTRODUCTION OF METALLIC PARTICLES TO ENABLE FORMATION OF METALLIC CARBIDES IN A MATRIX
A method of forming a ceramic matrix composite includes depositing particles on a ceramic fabric formed from a plurality of ceramic tows, applying a binder to at least the particles to form a stabilized ceramic fabric, forming a preform using the stabilized ceramic fabric, and densifying the preform. The ceramic tows are formed from a first material and the particles are formed from at least a second material.
Honeycomb filter
The honeycomb filter of the present invention comprises a ceramic honeycomb substrate formed from a porous body of sintered ceramic particles, and a filter layer formed on the surface of the cell walls, wherein a portion of the filter layer penetrates from the surface of the cell walls into pores formed by the ceramic particles to form inter-particle filtration bodies, these inter-particle filtration bodies are formed from a plurality of spherical ceramic particles and crosslinking bodies which bind the spherical ceramic particles to each other, and the spherical ceramic particles and the crosslinking bodies form a three-dimensional network structure.
Processes for making a super-insulating core material for a vacuum insulated structure
A method for forming a super-insulating material for a vacuum insulated structure includes disposing glass spheres within a rotating drum. A plurality of interstitial spaces are defined between the glass spheres. A binder material is disposed within the rotating drum. The glass spheres and the at least one binder material are rotated within the rotating drum, wherein the binder material is mixed during a first mixing stage with the glass spheres. A first insulating material is disposed within the rotating drum. The binder material, the first insulating material and the glass spheres are mixed to define an insulating base. A second insulating material is disposed within the rotating drum. The secondary insulating material is mixed with the insulating base to define a homogenous form of the super-insulating material, wherein the first and second insulating materials occupy substantially all of the interstitial spaces.

Carbon material and method for producing same
(Problem) In conventional method for producing artificial graphite, in order to obtain a product having excellent crystallinity, it was necessary to mold a filler and a binder and then repeat impregnation, carbonization and graphitization, and since carbonization and graphitization proceeded by a solid phase reaction, a period of time of as long as 2 to 3 months was required for the production and cost was high and further, a large size structure in the shape of column and cylinder could not be produced. In addition, nanocarbon materials such as carbon nanotube, carbon nanofiber and carbon nanohorn could not be produced. (Means to solve) A properly pre-baked filler is sealed in a graphite vessel and is subsequently subjected to hot isostatic pressing (HIP) treatment, thereby allowing gases such as hydrocarbon and hydrogen to be generated from the filler and precipitating vapor-phase-grown graphite around and inside the filler using the generated gases as a source material, and thereby, an integrated structure of carbide of the filler and the vapor-phase-grown graphite is produced. In addition, nanocarbon materials are produced selectively and efficiently by adding a catalyst or adjusting the HIP treating temperature.
