将研制的Ｎａ２ Ｏ－ Ｂ２ Ｏ３ － Ａｌ２ Ｏ３ － ＳｉＯ２ 系统玻璃， 利用粉末成珠工艺制成１～２ ｍ ｍ 粒径的玻璃珠， 再经分相热处理、酸溶、水洗， 得到了气孔率为２５ ％ 左右的吸附载体用的多孔玻璃珠。
The glass system of Na2 O 2 O 3 O 3 - Al 2 O 3 - SiO 2 system was made by the process of powder beading. The glass beads with the diameter of 1 ~ 2 m were prepared. The glass beads with the diameter of 1 ~ 2 m were further heat treated, acid - Porous glass beads for adsorption carriers at around 25%.
