ジャーナル フリー1気圧の窒素とアルゴンをキャリヤ・ガスとしてベンゼンを1600℃で熱分解した。析出したままのものと, 真空中2200℃で処理したものとについてX線散乱を調べた。これと比較するためにマダガスカル天然黒鉛を圧着して作った配向性の大きい試料を用いた。大角散乱域における0002線の幅から求めたパイロカーボン結晶粒子は, この熱処理によって約3倍に成長したが配向度は少し悪くなっている。小角散乱域の強度分布からみた粒子の大きさは熱処理によってあまり変っていない。
異方性を調べるために小角X線カメラには直径0.5mmのピンホールを用いた。X線が層に直角に入射すると散乱像は対称的で円となる。層に平行に入射すると像は非対称的で散乱角は層に直角な方向に大きく, 平行方向には小さい。この小さい方向の散乱は, 層に直角にX線をあてた場合の散乱角に一致する。この結果は板状の粒子が平行に配向している構造を考えると理解できる。抄録全体を表示PDF形式でダウンロード (4915K) -

ジャーナル フリーIn a general way, on the mixing process for carbon products, we have to add a large amount of binder, in order to bind carbon particles, and sometims this causes inhomogeneity or breakage.
To improve these faults, coaltar, pitch or synthetic resins is emulsified with water in use of emulsifying agent.
The filler substance is bound with emulsion binder by the usual mixing process, or the slurry mass of the mixture diluted with water is treated in the spray drier and turned into binder-coated particles that contained a proper amount of the binder to be needed to bind carbon particles. Thus we can get the baked body which is homogenous, without cracks, mehanically strong, after being baked in usual baking furnace or in an innert atmosphere without packing cokes.
Especially. the manufacture of carbon products in which is used carbon black is difficult, because they become inhomogeous or being broken on baking process. It becomes easier with use of emulsion binder.抄録全体を表示PDF形式でダウンロード (1571K) -

ジャーナル フリーFavorable flow properties of carbon paste are required for Söderberg anodes of aluminium reduction cells and for the extrusion of carbon products, however, the carbon industry still lacks in the adquate knowledge of the rheological properties of paste. The flowability test and the extrusion test were carried out in order to study correlation between the flow properties of paste and the qualities of the binder.
The flowability of the paste increases with the increase of temperature, but becomes nearly constant at temperatures over 70-80°C above the softening point in the flowability test and over 40-50°C above, in the extrusion test. The maximum flowability at temperature-insensitive range decreases with the increase of the percent of quinoline insoluble, acting as a coke flour, of the binder. When the flow behaviour of paste is measured at high shear stress by the extrusion test, the quinoline insoluble matter has a little effect on the extrusion pressure. The correlation between the temperature susceptibility of flowability and the properties of the binder is not detected for pitches used in this experiment.抄録全体を表示PDF形式でダウンロード (2691K) -

ジャーナル フリーVarious methods to test the surface functional groups of carbon blacks, …pH, volatile matter, hydrogen uptake from NaBH4 solution, vacuum pyrolysis, and the changes of the composition of the oxygen atmosphere heated in contact with carbon black … were examined.
As samples, acetylene, channel, furnace and thermal blacks were used.
The vacuum pyrolysis was experimented up to 1200°C at the rate of 200°C/hr, aad the evolved gas every 200°C intervals was analysed. The results showed the characteristics of the surface groups of the black samples, and CO2+CO gas increased in order of acetylene<thermal<furnace<channel.
In the experiment of oxygen atmosphere change heated with carbon black, the results indicated the same tendency mentioned above, in respect of surface reactivity of the four blacks used.
And the results of various methods used in the experiment, were compared and discussed respectively.抄録全体を表示PDF形式でダウンロード (1452K)
