Abstract
ก่อนการตกผลึกแบบใช้สารระเหยของสารละลายแอมโมเนียม ทังทังสเตท (APT) เติมสารประกอบของอะลูมินัม เช่น สารละลาย อะลูมินัมซัลเฟทลงเพื่อตกตะกอนสิ่งปะปนที่เป็นซิลิคอน และ ฟอสฟอรัสผลผลิตของแอมโมเนียม พาราทังสเตทที่ตกผลึกจะ 5 เพิ่มขึ้น Before crystallization using volatile ammonium tungstate (APT) solutions, aluminum compounds such as aluminum sulfate are added to precipitate silicon and phosphorus contaminants. The crystallized parasite state will increase by 5.
