Description
‐化学組成加えて、焼成された製品の構造が主に重要な役割を果たす。
‐開放細孔率に対する絶対値は重要ではない。細孔の型と形成は、しかしながら、製品特性に強い影響を与える。細孔率は同じように、特定のバッチ要素、及び粒子サイズの選択によって特に影響を与えられうる。
‐同じことが構造弾性に適用される。
‐要求される製品は、粗いMgO粒子が微細粒子(<100μm)のバッチ要素に起因するMA(MgO・Al2O3)スピネルに基づくマトリクスを有している構造によって達成される。
‐マトリクスは主に、よくても完全に、MAスピネルから成るべきである。最大限でも、遊離MgO粒子の最小の容量が本発明によって容認される。それに関して、その容量は全体のマトリクスに基づいて、<1.0質量%、最も良くて<0.5質量%、または<0.1質量%であるべきである。
‐前記マトリクスのMAスピネルは、事前に合成されて、バッチ要素となりうる。スピネルが焼成の際に比例的にそのままで形成される場合、それは有利的である。バッチ内の酸化アルミニウム(Al2O3)はそれによって、MgO微細粒子の容量及び/またはMgO粗粒子の表面積と反応する。相改善(phase reformation)(MAスピネルのそのままの形成)は体積の増加に関連付けられている。
‐MgO及びMAスピネルの異なる熱延長及び収縮は、二つの構造相の間に亀裂状キャビティを形成するために使われる。
‐開放細孔率は、微粒子マトリクスの内部で、及び粗粒子の周りの亀裂状(ギャップのような)細孔によって決定される。細孔は粗く粒状にされた(たいてい密度が高い)MgO粒子上で終わる。
‐MgO粗粒子の容量は、50質量%より上にあるべきである。例えば、52から60質量%である。残りは主にMAスピネルマトリクスによって特徴づけられる。
‐製品特性は、MgO粗粒子及びバッチの微粒子成分の間の粒子ギャップによって影響が与えられうる。バッチにおいて、MgOの粗粒子は>0.5mm、または>1mmの粒子サイズで利用されうる。マトリクスを形成すべき構成要素が、(d90)<100μm、しばしば同じく<50μmで主に用いられる。粒子サイズは焼成においてほとんど変化しない。しかしながら、焼成、及びそれ故小さな個々の粒子の結合、またはバッチ粒子の間のブリッジの形成がある。前記粒子は、粒子の表面上のスピネル形成に起因していくらか「成長」する。
‐ガラスタンクのリジェネレーター、特にそのようなリジェネレーターの硫酸塩濃縮ゾーンにおいて、特に還元条件の下での利用に対する(チェッカーれんがのような)れんが。

Claims (8)
- 最大1500℃の適用温度で5質量%未満の溶解相を形成する焼結耐火製品であって、
前記製品の構造は、d90>300μmの粒子サイズを有するMgO粗粒子(第2の構造相)が存在するMAスピネルマトリクス(第1の構造相)を備えており、
前記製品は、MgO粗粒子とMAスピネルマトリクスとの加算が98質量%より大きく、
三次元亀裂状細孔は前記二つの構造相の間に形成されていることを特徴とする製品。 - 前記亀裂状細孔は、MgO粗粒子の表面の50%を超えて延びていることを特徴とする請求項1に記載の製品。
- 前記亀裂上細孔は、MgO粗粒子の体積容量の最大1/20を備えている請求項1に記載の製品。
- 最大20%v/vの開放細孔率を有している請求項1に記載の製品。
- 50MPa以上の冷間圧縮強さを有している請求項1に記載の製品。
- 前記MgO粗粒子の容量は、50質量%を超える請求項1に記載の製品。
- 前記MgO粗粒子の容量は、60から80質量%の間である請求項1に記載の製品。
- 500μmより大きい前記MgO粗粒子の粒子サイズd90を有する請求項1に記載の製品。
