- 所定の焼成温度で焼成したセラミックスからなる反射板の反射率を向上させるセラミックス反射板製造方法において、
特定の組成のセラミックスについて焼成温度の低下に伴って焼成後の吸水率及び反射率が増加するセラミックスの特性を調べ、
そのセラミックスの特性を用いて、焼成温度の低下と焼成後の吸水率の増加との関係から焼成温度の低下に伴って吸水率が急激に増加する変曲点の焼成温度を求めるとともに、焼成温度の低下と焼成後の反射率の増加との関係から所望の反射率となる焼成温度を求め、
吸水率が急激に増加する変曲点の焼成温度と所望の反射率となる焼成温度との間の焼成温度でセラミックスを焼成してセラミックスからなる反射板を製造することを特徴とするセラミックス反射板製造方法。
