Abstract
Description
各実験を行うために、耐火ブロック材料のサンプルを最初に室温で試験炉内に装着した。次に、炉から周囲雰囲気をパージするために、還元雰囲気を約1時間の間サンプル上に流した。このステップに続いて炉を約1,200℃に加熱し、その後サンプルに還元雰囲気を流し続けながら、約4時間の間その温度で保持した。次に炉を室温に冷却し、また還元雰囲気を流すのを中止した。次いでサンプルを炉から取り出した。
コーニング社から入手可能なGorillaガラスのシートを、ガス前処理プロセスを受ける各サンプル上に置き、サンプルおよびガラスを室温で試験炉内に装着した。次に、炉から周囲雰囲気をパージするために、還元雰囲気を約1時間の間サンプル上に流した。このステップに続いて炉を約1,200℃に加熱し、その後サンプルに還元雰囲気を流し続けながら、約1時間の間その温度で保持した。次に炉を室温に冷却し、また還元雰囲気を流すのを中止した。サンプルを次いで炉から取り出し、ガラスとサンプルとの間の境界面の気泡の検査を目視で行った。実験結果を表3に明記する。
