The invention provides quartz glass as well as a preparation method and application thereof, and the preparation method comprises the following steps: starting flame to heat a substrate, then adding raw materials, reacting to generate silicon dioxide particles, and depositing on the substrate to generate an initial quartz ingot; according to the contact angle theta, the diameter R, the height h and the edge distance d of the quartz ingot, the flame enthalpy value and the raw material feeding rate are adjusted, and the quartz ingot is expanded; when the edge distance d is reduced to 0.05 R-0. 15R, descending the substrate, keeping the height of the deposition surface unchanged, and adjusting the flame enthalpy value and the raw material feeding rate at the same time, so that the diameter of the quartz ingot is further increased; and when the diameter of the quartz ingot is the same as that of the substrate, adjusting the flame enthalpy value, and then keeping the flame enthalpy value, the raw material feeding
