 Appearance : colorless cubic crystals, white or gray, grainy , cellular [ massive, spherical, irregular granular powder. Non-toxic , odorless , slightly bitter taste .

Relative density : 2.15 (25 ℃)
 
Melting point : 782 ℃
Boiling Point : 1600 ℃ to ] on .
Hygroscopic , easily deliquescence exposed to air .
Solubility: soluble in water, and release a lot of heat , which was slightly alkaline aqueous solution . Soluble in alcohol , acetone, acetic acid. With ammonia or ethanol effects were generated CaCl28NH3 and CaCl24C2H5OH complexes. Crystallization solution is precipitated at low temperatures hexahydrate was gradually heated to 30 ℃, is dissolved in its own crystal water, and heating continued gradual evaporation of water , up to 200 ℃ into dihydrate , and then heated to 260 ℃ then becomes white porous anhydrous calcium chloride.
Also known as ice calcium. As colorless crystals . General merchandise is white , off-white or slightly yellow solid flakes or lumps , bitter and astringent. Density 1.85g/cm3 (20 ° C). Soluble in water, soluble in alcohol , insoluble in ether. Their solution was neutral or slightly alkaline. Corrosive. When heated to 260 ℃ dehydration becomes anhydrous. Strong deliquescence . Method ammonia alkali distillation soda production waste ( containing calcium chloride 100g / L), after purification , clarification, evaporation , separation of sodium chloride , and the mother liquor clarification continue concentrated calcium chloride content of 70% when cooling system. Hydrochloric acid and limestone powder can also be used in the reaction. Used as refrigerants, antifreeze , fire extinguishing agents , for melting ice and snow melting , manufacturing anhydrous calcium chloride , flame retardant cotton fabric , rubber production of condensate agent. Can accelerate the hardening and increased tolerance to cold concrete building mortar , but also used as anti-fogging agent port and road dust agent. From industrial grade saturated solution of calcium chloride dihydrate , add bleaching agents, in addition to heavy metals agents, in addition to arsenic solution purification , filtration to remove impurities, liquid cooling and crystallization , solid-liquid separation, drying food grade product can be obtained . Coagulant used for canning and soy , calcium supplements .

Usage 
 
 
Use one: as refrigerants, but also for food processing, pharmaceutical and other 
Use two: calcium supplements used in the food industry, chelating agents, curing agents and freezing refrigerant. 
Use three: Calcium supplements for animal feed. 
Uses four: coagulant, China provides appropriate use according to production needs in soy. 
Five Uses: used as refrigerants (such as a refrigerator when chilled brine, ice and popsicles made ​​with frozen brine), antifreeze, automotive antifreeze, fire extinguishing agents. Used to melt ice and snow melt, cotton fabric finishing and finishing of flame retardants. Used as adhesives and wood preservatives. Anhydrous calcium chloride raw material is manufactured. For wall stucco and plastering jobs, increase clotting ability. Rubber production is used as condensate agent. Mixing starch paste is used as a sizing agent. Also for non-ferrous metal smelting. Used as pharmaceuticals. 
Uses Six: oxygen, sulfur absorbent. Food Protection agent. Sizing agent. Purifying agent. Antifreeze.
