Description
(1)少なくとも0.1重量%(wt%)のTiO2および多くとも10重量%のY2O3と混合された複数のジルコン粒子を提供し、
(2)該粒子を静水圧プレス加工して未焼成体を形成し、
(3)該未焼成体を少なくとも1500℃の温度で焼結させて、緻密な焼結されたジルコン材料を得る、
諸ステップを含み、
(a)ステップ(1)において提供されたジルコン粒子が多峰性の粒子サイズ分布曲線を有する。
フュージョン法は、シートガラスを生産するためのガラス作製法に用いられる基本的な技術の一つである。例えば、Varshneya,Arun K, ”Flat Glass,”Fundamentals of
Inorganic Glasses,Academic Press,Inc.,Boston,1994,Chapter 20,Section 4,2.,534-540 を参照されたい。例えばフロート法およびスロット・ドロー法等の他の従来技術の方法と比較して、フュージョン法は、卓越した平面度および平滑度を備えたガラスシートを生成させる。その結果、このフュージョン法は、液晶ディスプレイ(LCD)の製造に用いられるガラス基板の製造に特に重要になって来ている。
“Plastic Deformation,Viscous Flow,and Creep,”Introduction to Ceramics,2nd edition,John Wiley & Sons,New York,1976,704-767 および特に等式14.9を参照されたい。歪みを時間で微分したものであるクリープ速度の単位は長さ/長さ/時間である。等式(1)のクリープ速度は、応力の累乗、すなわちσnで変化するので、ここでは等式(1)の使用を「指数法則モデル」と呼ぶ。
米国特許第5,124,287号は、ジルコン耐火物の耐熱衝撃特性を改善するために、微粒子形態のジルコニアの使用に関するものである。焼結時の結晶成長を促進するためにチタニア粒子が採用されている。この特許の請求項にはチタニア濃度が0.1重量%と4重量%の間と記載されている。好ましいチタニア濃度は1重量%であり、膨れが問題になる場合には、僅か0.1重量%のチタニアが用いられる。この特許は、0.2重量%のチタニア濃度を有する“grog”(高耐熱性材料)がそのいくつかの実施例のための出発材料として用いられたことを説明している。
