The characteristics of different types of cryolite

Cryolite can be divided into high molecular ratio cryolite and low molecular ratio cryolite according to the molecular ratio of sodium and aluminum. And this one is divided into sand cryolite, granular cryolite and powdered cryolite according to its physics class. Different shapes, functions and requirements are also different. We can choose the right product according to our needs. Next, I will give you the cryolite manufacturer-Zhengzhou Tianzhirui New Material Co., Ltd. to explain to you.

  一. Features of sand-like cryolite

  1. Low melting point and fast melting speed, which can shorten the test piece that enters the normal working state

  2. The molecular ratio can be adjusted in a larger range, which can adapt to the different requirements of the cryolite molecular ratio in different periods of the electrolytic cell

  3. Low moisture content, low fluorine loss

  4. Granular, good fluidity, good for conveying

   5. The raw materials are easily available and the production cost is low.

   2. The characteristics of powdered cryolite

   1. A higher particle size can be achieved, usually above 200 mesh;

  2. The molecular ratio can reach 1.75-2.5, with good adjustability;

  3. Ultra-fine products with a pass rate of over 98% for 325 mesh, which can meet the requirements of special industries for cryolite.

   Three, the characteristics of granular cryolite are

   1. Good fluidity, dust pollution, suitable for mechanized cutting;

  2. High actual yield in electrolytic production, which can reduce the cost of electrolytic aluminum;

  3. The molecular ratio is between 2.5-3.0, which is especially suitable for the opening of the electrolyte;

   4. The particles are mostly 1-10mm.

   With the year-on-year increase in the demand for macromolecular cryolite in my country's aluminum industry and the increasing awareness of environmental protection, the production technology of macromolecular cryolite has made great strides forward. The above are the characteristics of different shapes of cryolite. It is recommended that you choose the right product according to your needs.
