Description

Technical Field

[0001] The utility model relates to the field of perovskite processing, and in particular to a perovskite magnetic stirring reaction kettle. Background Art

[0002] Perovskite refers to a type of ceramic oxide with the general molecular formula ABO3. The earliest discovered oxide of this type is a calcium titanate (CaTiO3) compound present in perovskite, hence the name. Since this type of compound has many structural characteristics and is widely used and studied in condensed matter physics, physicists and chemists often refer to it by the ratio of each compound in its molecular formula (1:1:3), hence the name "113 structure". It is a cubic crystal. In cubic crystals, there are often parallel crystal edge stripes, which are the result of polysynthetic twinning when the high-temperature variant transforms into the low-temperature variant.

[0003] Since the processing of perovskite requires the use of a corresponding reactor, such as a magnetic stirring reactor in the prior art, the existing magnetic stirring reactor will cause leakage when the sealing between the stirring shaft and the reactor cover is not tight, thus affecting the overall reaction performance; at the same time, the magnetic contact points between the stirring shaft and the motor are mainly concentrated at one end close to each other, so that the magnetic contact area is limited and power cannot be fully transmitted.

[0004] Therefore, it is very necessary to invent a perovskite magnetic stirring reactor. Utility Model Content
