Lithium orthosilicate (Li4SiO4) powder was synthesized by the solid-state reaction of lithium oxide with amorphous silica, and the effects of fabrication parameters on the structural characteristics of the product were investigated. Processing considerations such as milling media, drying technique, calcination time and temperature, pressing behavior, sintering time and temperatures, and impurity concentration were addressed. The initial powder particle size was observed to be important in achieving high sintered density, with densities as high as 98% TD achieved with a particle size of approximately 1 μm.
オルソケイ酸リチウム（Li4SiO4）粉末を、酸化リチウムと非晶質シリカの固相反応により合成し、生成物の構造特性に及ぼす作製パラメータの影響を調査した。粉砕媒体、乾燥技術、仮焼時間と温度、加圧挙動、焼結時間と温度、不純物濃度などのプロセス上の考慮事項を検討した。初期粉末の粒子径が高い焼結密度の達成に重要であることが観察され、約1 μmの粒子径で98% TDもの密度が達成された。
