Zusammenfassung: | To provide a method for manufacturing a ceramic composite, capable of controlling the size of a lamellar structure for uniformly scattering primary light and wavelength converted secondary light.SOLUTION: A method for manufacturing a ceramic composite 2 comprises: storing a plurality of dice 9 having slits and having longitudinal directions arranged in parallel in a crucible and inputting a raw material including at least aluminum oxide, yttrium oxide, magnesium oxide and cerium oxide into the crucible; heating the crucible to melt the raw material in the crucible and prepare a melt 21; forming a melt pool 22 for storing the melt in an upper portion of the slit through the slit; and contacting a seed crystal 17 to the melt pool to pull the seed crystal at a pulling speed of 0.9 mm/hour or more and 400 mm/hour or less.SELECTED DRAWING: Figure 7
【課題】一次光と波長変換された二次光を均一に散乱するラメラ構造のサイズを制御することが可能なセラミック複合体の製造方法の提供。【解決手段】スリットを有すると共に、各々の長手方向が平行に配置された複数のダイ9を坩堝に収容し、坩堝に少なくとも酸化アルミニウム、酸化イットリウム、酸化マグネシウム、および酸化セリウムを含む原料を投入する工程と、坩堝を加熱して、原料を坩堝内で溶融して融液21を用意する工程と、スリットを介してスリット上部に融液を溜めた融液溜まり22を形成する工程と、融液溜まりに種結晶17を接触させ、種結晶を引き上げ速度0.9mm/時間以上400mm/時間以下で引き上げる引き上げ工程を有するセラミック複合体2の製造方法。【選択図】図7 |
