Problems solved by technology

In addition, nickel metal is magnetically conductive, and the thickness of the coating material (target material) will affect the cathode magnetic field. The thickness of the target material is generally 2-3mm. In industrial production, due to the thin thickness of the nickel target, the consumption of the nickel target is too fast, resulting in an increase in the replacement frequency of the nickel target. Affect production efficiency
Due to the above reasons, the cost of smart glass is currently high and the progress of industrialization is slow.

Abstract

The invention discloses a preparation method of an intelligent glass anode electrochromic layer coating material. A relative target material is manufactured by using a mode of slip casting and vacuumhigh-temperature sintering; vacuum treatment is carried out in a high-temperature sintering process, and a second element is added into nickel oxide, so that the conductivity of the material is improved through the electric carrier mobility generated by caused oxygen vacancy, the uniformity and the density of the target material are improved, the generation of abnormal electric arc during a sputtering process is greatly reduced, the service life and the utilization rate of the target material are prolonged, and the quality and the performance of the sputtering film are improved. A stable sputtering arc can be obtained by using a pulse direct current (DC) power supply, an alternating current (AC) power supply, an intermediate frequency (MF) power supply, or other power supplies in a sputtering process, and only the introduction of a small amount of oxygen is required in the sputtering process, so that dustfall is not easily caused. In addition, the process of staged heating sintering isadopted, and other gas is added into argon, so that the sputtering film forming rate can be increased by about 5-10 times, and the flatness and the large-area uniformity of the film can be improved.

Description
