Of these Hydroflouric acid has the most serious effect, even when it is present in PPM (parts per million) in solutions. Where as phosphoric acid and caustic solutions cause no problems when cold but at elevatrd temprature corrosion occurs. in case of caustic solutions upto 30% concentration can be handled safely at ambient temperature. Under actual operating conditions, the effect of turbulence, and traces of other chemicals in the solution may increase of decrease the rate of attack. So it is not possible to give exact figures for corrosion by caustic solutions. - > THERMAL PROPERTIES Linear coefficient of thermal expansion The coefficient of thermal expansion of borosilicate glass over the temperature 0 - 300�°C is 3.3 x 10-6/�°C. This is very low when compared with other glasses and metals. That is why, borosilicate glass is often called low expansion borosilicate glass. Specific heat Specific heat between 25C and 300C is average to be 0.233Kcal/Kg, C Thermal Conductivity Thermal conductivity is 1.0 Kcal/hr,mC. Over the permissible operating temperature range. - > RESHAPEING In the given below are shown characteristic temperature at a determined viscosity, essential for glass reshap. Lower cooling temperature 1024 poise 515C Upper cooling temperature 1013 poise 565C Softening point 107 poise 795C Reshapeing point 104 poise 120 C Specification of borosilicate glass 3.3
