Chemical data for borosilicate glass 3.3

Borosilicate glass represents unmatched standardized glass for construction of plant and piping in the chemical, dyestuff, food pharmaceutical, petrochemical industries. Its steadily growing use is due to many advantages over conventional materials.
- Outstanding corrosion resistance
- Smooth pore free surface.
- Transparency
- Catalytic inertness.
- No effect on taste and odour.
- Physiological inertness.

Borosilicate glass is chosen for its unique chemical and physical properties. Borosilicate glass can be considered as being composed of oxides. Silica (SiO2) Magnesia (MgO) and lead oxide (PbO) are the principle modifiers/fluxes.
The chemical and physical properties of any glass depends on a varying degree on chemical composition of glass.

- > CHEMICAL COMPOSITION

The composition of borosilicate glass used for chemical plants has following approximate composion.

- > RESISTANCE TO CHEMICAL

Borosilicate glass is inert to almost all materials except hydroflouric acid (HF) phosphoric acid((H3Po4) and hot strong caustic solutions. 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 25°C and 300°C is average to be 0.233Kcal/Kg, °C
Thermal Conductivity
Thermal conductivity is 1.0 Kcal/hr,m°C. Over the permissible operating temperature range.

- > RESHAPEING
