Description

technical field [0001] The invention relates to an intelligent device applied to liquid-phase chemical synthesis of raw materials, and is particularly suitable for the liquid-phase synthesis of raw materials for growing yttrium vanadate and its doped crystals by pulling method. Background technique [0002] Yttrium vanadate (YVO4) crystal is an excellent birefringent crystal material. Compared with traditional birefringent crystal materials - rutile, calcite and lithium niobate, it has large birefringence, large optical damage threshold, and good light transmission performance. , wide range of light transmission bands, deliquescence resistance, easy processing and other outstanding advantages. It is mainly used in optical isolators, circulators, optical beam splitters and infrared polarizers in optical fiber communication. [0003] Neodymium-doped yttrium vanadate (Nd: YVO4) is a laser crystal with excellent performance. The crystal has the characteristics of large a...

Problems solved by technology

However, there is still a big gap between the industrialization process of yttrium vanadate crystals in my country and the needs of technological development, and has not yet met the requirements of the development of traditional industries and high-tech fields in terms of quality and quantity; industrial system

The specific manifestations are: 1) The production equipment is backward, the control level is low, the output of a single machine is small, the yield rate is low, and the product quality is unstable, etc.; );

[0005] 3) The level of industrialization and engineering is low, and the development of raw materials and special equipment supporting crystal production is unbalanced; product application development needs to be strengthened, and disorderly competition among peers needs to be resolved

[0008] The technical problem to be solved by the present invention is to provide an intelligent liquid-phase synthesis reaction device to solve the shortcomings of the traditional liquid-phase synthesis method due to manual operation: serious waste of weighing, low accuracy, large randomness, and high labor intensity. Dangerous chemicals are prone to injury, the working environment is poor, the data cannot be verified, and the process reproducibility is poor
