A large-specification quartziferous ceramic heat accumulator is characterized by being of a column structure, a plurality of channels penetrating through a column body are formed in the heat accumulator, and the heat accumulator is formed by sintering inorganic powder and an additive, wherein the inorganic powder is prepared from, by weight, 15-20 parts of quartz stone, 15-20 parts of mullite, 9-15 parts of cordierite, 7-13 parts of kaolin, 13-18 parts of potassium feldspar, 2-4 parts of silicon nitride, 3-5 parts of boron nitride and 2-4 parts of alpha-aluminum oxide. The large-specification quartziferous ceramic heat accumulator has high formability and shape preserving performance. By means of the formula and the production method, the channels of the heat accumulator are dense, the wall thickness is small and is only 1 mm, the section size is large and is larger than 100 cm<2>, the length-diameter ratio is high, the length reaches 100 mm, and the channels have the advantages of being small in resistance, capable of capable of ensuring little dust accumulation, not prone to blockage, high in dust discharging performance and the like.
