The invention relates to the technical field of glass manufacturing and aluminum oxide ceramic connection, and discloses glass, an aluminum oxide ceramic-glass structural part, a preparation method and application. The glass provided by the invention comprises the following chemical components in terms of oxides on the basis of the total weight of the glass: 8-15 wt% of sodium oxide, 10-15 wt% of boric oxide, 60-80 wt% of silicon oxide, 0-5 wt% of lithium oxide, 0-5 wt% of aluminum oxide, 2-5 wt% of magnesium oxide and 1-5% of calcium oxide, wherein the total weight content of (sodium oxide and lithium oxide) is less than or equal to 18wt%, the total weight content of (silicon oxide and boron oxide) is 75-85wt%, and the weight ratio of (sodium oxide, lithium oxide and calcium oxide) to (magnesium oxide, boron oxide and aluminum oxide) is 0.7-1.4. The glass has excellent connecting performance, the joint of the glass and an aluminum oxide ceramic structural part has high mechanical strength, the linear thermal expansion coefficient of the glass is close to that of aluminum oxide ceramic, the cracking risk in the cooling process after welding can be reduced, meanwhile, the light transmittance of the glass is larger than or equal to 90%, and the service life of the glass is prolonged. And the requirements of visualization or optical signal transmission in an aluminum oxide-glass structural member can be met.
