図14は、800℃の焼結スケジュール後のバットシールに関するEagle2000に対する不一致データを示している。示されているのは、721UT(図10から)、並びにBM5−721UT(以下と図14では、単に721UTで表されている)および88MOCと称される詰まったZn含有β石英により製造された2つのブレンドである。これらのブレンドは、ブレンド6500(90%の721UT+10%の88MOC、質量基準)、およびブレンド6513(15%の88MOCすなわち85%の721UT+15%の88MOC)と特定される。充填剤の添加量を増加させると不一致が累進的に改善される(すなわち、フリットは、累進的に低い張力下になる)ことに留意されたい。また、組成物中に上述した充填剤のいずれかが存在することは、HTS結晶化層に影響を与えると考えるべきではなく、HTS結晶化層のどのような変形からも排除されるべきである。
