(57) [Summary] [Structure] The composition of the main component of the matrix is glass phase 2 5 to 70 wt% and a crystal phase of 75 to 30 wt%, and the chemical composition of the main component constituting the glass phase is 10 0%, K 2 O + Na 2 O 4-12 wt%, SiO 2 50- 75% by weight, Al 2 O 3 17 to 40% by weight, and the mineral composition of the main component constituting the crystal phase is 10 to 60% by weight of α-alumina, 0 to 20% by weight of quartz, and mullite 2 to 2 with respect to the entire base material as 100%. A solute matrix characterized by being 20 wt%. [Effect] According to the solute matrix and the method for producing the same of the present invention, the mechanical strength of the solute matrix can be dramatically increased, and other physical properties (hot deformability, thermal shock resistance, It is also possible to have no adverse effect on the calcinable temperature, etc.). This fusible base material can be applied to sanitary ware, large porcelain plates, various engineering ceramics, etc. In addition, when the high alumina base material is applied to large products, it is possible to provide a glaze with excellent matching with the base material.
