Abstract: PROBLEM TO BE SOLVED: To obtain a β-spodumene structure and further to provide a method for preparing the β-spodumene structure. SOLUTION: This method for preparing a β-spodumene structure comprises preparing a homogeneous plastic batch comprising an inorganic raw material, an organic binder and a vehicle, in which the inorganic raw material comprises about 75-95 wt.% mineral and about 5-25 wt.% glass. A green ware is formed out of the batch, and the green ware is fired to provide a structure substantially constituted of the β-spodumene, and having (0-800 deg.C) thermal expansion and >=4 Ksi strength.
