The invention discloses a method for manufacturing a ceramic tube for an explosionproof fuse for an automobile, comprising the following steps: S1, drying cordierite powder to the water content less than or equal to 0.03%, adding phosphorus trioxide, strontium carbonate, titanium dioxide, yttrium oxide and silicon dioxide into the dried cordierite powder according to a preset ratio, and uniformly stirring; S2, ball-milling the uniformly stirred mixture powder in a ball-milling machine, after ball-milling, a cement specific surface measurement value of the mixture powder being 500-600m2/kg; S3, adding white wax with 8-15 wt% of the mixture powder and yellow wax with 0.2-0.8 wt% of the mixture powder in the ball-milled mixture powder, and manufacturing a wax cake; and S4, hot-pressing and molding the wax cake and machining the ceramic tube for the exposionprood fuse for the automobile. The ceramic tube for the explosionproof fuse for the automobile is manufactured by the ceramic material with cordierite as a principal crystalline phase and has very low expansion coefficient so as to realize an anti-cracking effect.
