SILICAWARE

---

Chemical Properties              :  Not affected by Nitric, Sulphuric, Hydrochloric Acids.                            Certain Metal oxides, Hot Alkalies react with Silica. It is  attacked by  Hydrofluoric acid & Phosphoric Acid at high temperature.

Physical Properties               :  Density : 2.2 / cm³ , Hardness : 6 – 7 Mohs

Poisson’s Ratio                      :  0 – 17  , Tensile Stre ngth : 600 – 700 kgs/cm²

Softening Temperature       :  1700℃

Annealing Temperature      :  1150℃

Working Temperature         :  1900℃ to 2000℃

Operating Temperature      :  1050℃

(continuous)

Operating Temperature      : 1350℃

(intermittent)

Note : Continuous usage of silica ware above 1000℃  leads to breakage on repeated usage. For long usage it is advisable to since the silica ware in distilled water and alcohol to remove any remains of the material heated.
