発泡金属のみで成りたっているため、骨格構造の強度が
小さくなる欠点があった。Since it is composed only of foam metal, it has a drawback that the strength of the skeleton structure becomes small.
そこで、この発明は、従来の三次元骨格の金属多孔体に

材料を要旨としている。Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has a carbon three-dimensional skeleton structure substrate having a crystallite size La (Å) of 300 Å or less and a specific gravity of butanol dipping method of 1.70 g. Carbonaceous material consisting of glassy carbon of less than / cc, and the surface of the carbon three-dimensional skeleton structure substrate is covered with a nonmetallic thin film of Si, Al 2 O 3 or Si 3 N 4. The main point is composite materials.
所定の条件をみたすガラス状カーボンによって三次元骨
格構造の基材を構成し、その基材の表面に薄膜状にSi,A
l2O3またはSi3N4の非金属を被覆した。A substrate with a three-dimensional skeleton structure is composed of glassy carbon that satisfies the specified conditions, and Si, A is formed in a thin film on the surface of the substrate.
Non-metal coated with l 2 O 3 or Si 3 N 4 .
作用 基材がガラス状カーボンよりなり高強度を有するため、
フィルタ用複合材料の強度を大きくできる。Since the base material is made of glassy carbon and has high strength,
The strength of the composite material for filters can be increased.
また、非金属の薄膜の厚みを小さくしても、強度上の問
題が生じない。Further, even if the thickness of the non-metal thin film is reduced, the problem of strength does not occur.
実施例 三次元骨格構造のポーラスな軟質のポリエステル系ウレ

合物）を付着させる。たとえば、ウレタンフォームにフ
リフリルアルコール重合物を含浸させる操作において、
目詰まりがなく、かつ均一に含浸が行えるように遠心脱
液装置を用いて脱液するのが好ましい。Example A resin (for example, a furfuryl alcohol polymer) is attached to a porous and flexible polyester-based urethane foam having a three-dimensional skeleton structure. For example, in the operation of impregnating a urethane foam with a furfuryl alcohol polymer,
It is preferable to perform dewatering by using a centrifugal dewatering device so that impregnation can be performed and uniform impregnation can be performed.
そのあと、150℃で樹脂を乾燥硬化させる。しかる後、
非酸化性雰囲気（たとえば窒素雰囲気）において950℃
で焼成する。この焼成によりウレタンフォームは炭化
し、樹脂はガラス状カーボンとなり、骨格中に連通孔を
有するガラス状カーボン三次元骨格構造の基材を形成す
る。After that, the resin is dried and cured at 150 ° C. After that,
950 ° C in a non-oxidizing atmosphere (for example, nitrogen atmosphere)
Bake at. By this firing, the urethane foam is carbonized, the resin becomes glassy carbon, and a base material having a glassy carbon three-dimensional skeleton structure having communication holes in the skeleton is formed.
なお、前述の含浸→硬化→焼成の工程を複数回くり返し
たり、焼成後に純化のために塩素ガスと接触させながら
約2300℃で加熱してもよい。The above-mentioned steps of impregnation → curing → firing may be repeated a plurality of times, or heating may be performed at about 2300 ° C. while contacting with chlorine gas for purification after firing.
ガラス状カーボンの結晶子の大きさLa（Å）が300Åよ
りも大きいと、結晶子が大きすぎるため、強度の低下が
みられる。また、ブタノール浸漬法の比重が1.70g/ccよ
りも大きいと、製造が極めて困難となる。When the crystallite size La (Å) of glassy carbon is larger than 300 Å, the crystallite is too large and the strength is reduced. If the specific gravity of the butanol dipping method is higher than 1.70 g / cc, the production becomes extremely difficult.
前述のように作られた三次元骨格構造のガラス状カーボ
ン基材の表面にCVD法によりSi,Al2O3またはSi3N4の薄膜
を形成し、各骨格の表面を被覆する。A thin film of Si, Al 2 O 3 or Si 3 N 4 is formed on the surface of the glassy carbon substrate having a three-dimensional skeleton structure manufactured as described above by the CVD method to cover the surface of each skeleton.
薄膜の厚みは20μｍ未満であると三次元骨格構造の強度
が十分でなく、2mmを越えると三次元骨格構造の空隙が
少なくなるので20μｍ〜2mmが好ましい。If the thickness of the thin film is less than 20 μm, the strength of the three-dimensional skeleton structure is not sufficient, and if it exceeds 2 mm, the voids of the three-dimensional skeleton structure are reduced, so 20 μm to 2 mm is preferable.
CVD法以外の方法（たとえば、スパッタリング法、プラ
ズマ法、電解メッキ法、非電解メッキ法等）によって薄
膜を形成してもよい。The thin film may be formed by a method other than the CVD method (for example, a sputtering method, a plasma method, an electrolytic plating method, a non-electrolytic plating method, etc.).

しかも、ガラス状カーボンの結晶子の大きさLa（Å）が
300Å以下であるので、強度の低下を防止することがで
きる。Moreover, the crystallite size La (Å) of glassy carbon is
Since it is less than 300Å, it is possible to prevent the strength from decreasing.
さらに、ブタノール浸漬法の比重が1.70g/cc以下である
