The invention relates to low-expansion microcrystalline glass which takes spodumene tailings as a main raw material and a manufacturing method thereof. The raw materials of the low-expansion microcrystalline glass comprise alumina and lithium carbonate. The low-expansion microcrystalline glass is characterized in that the mixing proportion of the compositions by weight percentage is as follows: the content of the spodumene tailings which are taken as the main raw materials is between 70 and 80, the content of the alumina is between 9 and 14, and the content of the lithium carbonate is between 5 and 10; the sum of the addition of four compositions of zinc oxide, barium carbonate, a boric acid and magnesia is between 2 and 5; the sum of the addition of titanium oxide and zirconia is between 3 and 5; and quartz sand can replace partial spodumene tailings. The invention solves the problem of manufacturing the low-expansion microcrystalline glass by utilization of a large quantity of waste spodumene tailings, and the low-expansion microcrystalline glass has the characteristics of reducing environmental pollution, improving the product performance and reducing the production cost.
