The characteristics of potassium fluoaluminate

Mickey fluoride potassium aluminate is a colorless crystalline powder, at room temperature (25 ℃) the solubility of ghzo for 1.4299/1000.
Its composition is nKF·AIF3, and n is generally 1, 1, 3.
The industry is known as potassium cryolite.
It can be used in metallurgy, ceramics and welding departments, mainly used as soldering flux of aluminum and aluminum alloy, flux of glass ceramic industry and active packing of friction agent.
In particular, with the development of brazing process technology, it has been found that the total crystal components of AIF3 and KF are found in the same way (the weight % ratio is: 45.2% KF, 55.4 % AIF).
Potassium fluoaluminate is composed of 1.195KF· AIF.
The eutectic temperature is 560 ℃.
In the flux of aluminum, it has the advantage of much superior to chlorinated polycide, not hygroscopic, is known as "no corrosion" flux, so it is highly regarded by people.
