K2SiF6(40mol%)とKBr(60mol%)との混合物をグローブボックス内で秤量した。混合物(1グラム)をプラチナるつぼ内に置き、ムライト管炉へと移動させた。管炉を、Ar雰囲気で30分間パージし、続いて摂氏675度で1時間保持し焼成した(プラスマイナス摂氏3度/ArをKOHに通してバブリングした)。得られた溶融物をAr雰囲気中で30分間パージした。溶融物を入れたプラチナルツボを、炉から取り出し、メタノールで洗浄して過剰なKBrを溶解させた。バブラが清浄に見えることを観察し、K2SiF6の分解によるSiF4の形成がないまたは最小であることを確認した。
K2(Si,Mn)F6の焼結した部品を、開始材料のHIP(熱間等方圧加圧成形)を介しておよび/または透明もしくは半透明のセラミック部品を生成するためにさらに焼結することをともなう素地を作成することによって形成することができる。プロセスにおいて、粒子サイズを上手く制御することができ、そして少量のフラックス材料を添加して焼結および緻密化を向上させることができる。
