Yes, a mixture containing 42% NaCl and 58% CaCl2 melts at about 590 Celsius while pure sodium chloride melts at about 800 Celsius.

Why calcium chloride added in sodium chloride to lower the melting point?
The heat of dissolution for calcium chloride in water is greater compared with the same paremeter for sodium chloride; consequently the process of dissolution need more heat from the environment and the freezing point of the water solution is lower.
Why is CaCl2 used as salt to spread on streets in winter?
Calcium chloride is more efficient than sodium chloride because has a greater heat of dissolution and consecutively the temperature is greater and the melting of ice easier. Also calcium chloride is not so dangerous for the vegetation as sodium chloride. But calcium chloride is more expensive than sodium chloride. Also be sure that all the chlorides are corrosive for metals (the cars included).
Which is more expensive sodium chloride or calcium chloride?
The price is higher for the calcium chloride.
What does sodium carbonate plus calcium chloride form?
Calcium carbonate (insoluble in water) is obtained and sodium chloride.
How do you separate sodium chloride from calcium carbonate?
Dissolve the sodium chloride(which is actually salt) in water. Then, filter the calcium carbonate with the help of filter paper. Crystallize the solution of sodium chloride with water... Hope this helps! :)
Why calcium chloride is added with sodium chloride in metallurgy of sodium?
Because the mixture NaCl + CaCl2 has a lower melting point that NaCl.
What is the melting of sodium chloride?
The melting point of sodium chloride is 801 0C.
Does sodium chloride contain calcium chloride?
Pure sodium chloride doesn't contain calcium chloride.
What is the name of the mineral that is commonly use for melting winter ice on slippery winter surfaces?
mixture of sodium chloride and calcium chloride
What is the name of the mineral that is commonly use for melting winter ice on slippery winter surfaces.?

What is the melting characteristic of sodium chloride?
The melting point of sodium chloride is 801 0C.
What it sodium chloride melting point?
The melting point of sodium chloride is 801 0C.
Can salt and chemicals melt the snow completely?
Salts (sodium chloride, calcium chloride) are added to reduce the melting point of ice; also the heat of dissolution contribute to the melting.
Is sodium chloride an electrolyte?
As for your body, the major electrolytes are as follows:sodium (Na+)potassium (K+)chloride (Cl-)calcium (Ca2+)magnesium (Mg2+)bicarbonate (HCO3-)phosphate (PO42-)sulfate (SO42-)

Do calcium carbonate and sodium chloride react?
Calcium carbonate and sodium chloride doesn't react.
