在微波介電材料中，Ba2Ti9O20具有高介電係數，低溫度係數及介電損失。由文獻中發現添加SnO2可以穩定Ba2Ti9O20的相，所以本實驗添加2 mole% SnO2經煆燒後，便可成相；而且燒結後，塊材微波特的測量可與市售品相同( K = 37、Q = 27500 )。
由Ba2Ti9O20與BBS玻璃擴散偶實驗中，發現有二次相BaTi(BO3)2的析出，欲以BaTi(BO3)2、BBS及TiO2披覆的方法阻止反應，卻依然會有二次相產生。而固態法製作BaTi(BO3)2的塊材，經1000℃燒結後，可以得到微波特性K = 11.5、Q = 23000。
低溫燒結Ba2Ti9O20的厚膜，雖然會有二次相，但是有比較好的微波特性。體積比(Ba2Ti9O20：BBS)5：5在900℃燒結有最大K值=13.7；體積比(Ba2Ti9O20：BBS)8：2在900℃燒結有最大Q值=1600。故以此厚膜進行無收縮基板的製作。
將添加BBS玻璃比例多及少的厚膜疊層，以含玻璃比例少的厚膜為抑制收縮層，經燒結後可得到表面緻密、不收縮，而且微波特性佳(K值=11，Q值=1150)之陶瓷基板。
