Robuster Quartz Fused Quartz Labware - Broad Base

Robuster Quartz Fused Silica Ceramics features excellent thermal reliability under high temperature (up to 1350˚C), resistivity to chemical corrosion and thermal shock; Our Silica ceramic products are widely used in chemical, medical and biology industries for chemical synthesis/analysis/a ctivation, and calcination applications. Manufactured via slip casting process, combining the advanced processes from ceramic fabrication and powder metallurgy, our silica ceramic products are developed with outstanding purity, high density, low porosity, superior thermal properties. Below are the technical parameters of silica ceramic labware products: Parameters Value Comment Purity of SiO2 >99.9% Thermal Expansion Coefficient (CTE) <0.54×10-6/℃（average ） Operating Temperature 1200℃ for long term use; 1350℃ and above for short period use Anti-thermal shock 1100℃ quickly dip in 25℃ cold water, no crack for 10 times cycle Density 2.19g/cm 3 (normal fused silica ceramic is 1.9g/cm3), No shrinkage at high temperature Porosity <1% Smooth and shining surface Chemical Stability Inert to most acid, base, metal and metal oxide Reactivity with other elements Metal Temperature Acid Temperature Oxide Temperature Ag ★ H2SO4 ★ Al2O3 1000℃ Al 800℃ HNO3 ★ BaO 900℃ Au ★ HCL ★ CaO 900℃ C 1000℃ HF Readily at all temperatures CuO 800℃ Ca 600℃ Fe(Oxides） 900℃ Cd ★ MgO 900℃ Ce 800℃ H3PO4 200℃ PbO 800℃ Hg ★ Organic ★ ZnO 900℃ Li 250℃ Basic Oxides 800℃ Mg 800℃ Gas Temperature Mo ★ Pb ★ Br2 Cl2,I2,S ★ ★ No reaction Pt ★ F2 ☆☆ ☆☆No reaction when dry (reacts as HF if wet) Sn ★ HCl,SO2 ★ W ★ NO2,H2 ★ Zn ★ N2,O2 ★ Standard sizes below for each silica ceramic labwares can satisfy the needs for most applications, however we do accept orders with custom shape and dimensions based on customer needs.
