Product Name: Ceramic Crucible Material: Thickened high-quality heat-resistant ceramic High Temperature Resistance: Approximately 1250°C Specifications: 10mL - 300mL (Smooth glazed surface)
Product Introduction: The crucible is an essential component of chemical instruments. It serves as a container for melting and refining metal liquids as well as for solid-liquid heating reactions, ensuring the smooth progress of chemical reactions.
Operational Guidelines: For optimal performance, the crucible can withstand temperatures up to approximately 1250°C when used according to standard procedures. The heating rate should be controlled at around 5-10 degrees Celsius per minute; sudden increases in temperature should be avoided.
Material Composition: Aluminum Oxide (Al₂O₃): 36.49% Silicon Dioxide (SiO₂): 60.21% Titanium Dioxide (TiO₂): 0.48% Iron Oxide (Fe₂O₃): 0.21% Calcium Oxide (CaO): 0.31% Potassium Oxide (K₂O): 1.17% Sodium Oxide (Na₂O): 0.75% Loss on Ignition (LOI): 0.11%
