Flat bottom clear silica quartz crucible

 

Quartz crucible

The quartz parts made from natural quartz after the process of melting and fine grinding. It has high purity, heat resistance and corrosion resistance, also be low coefficient of thermal expansion.

 

Flat bottom clear silica quartz crucible for melting:

1.High SiO2 Content: Made from high-purity fused quartz with an SiO2 content of >99.9% (up to 99.99%), ensuring minimal contamination of the melt .

2.Contamination-Free: Chemically inert to most acids and bases, safeguarding the integrity of sensitive materials like silicon or precious metals .

3.Exceptional Thermal Shock Resistance: Withstands extreme temperature changes (e.g., quenching from 1100°C into cold water without cracking), ensuring durability during rapid heating/cooling cycles .

4.High Softening Point: Operates reliably at high temperatures with a softening point around 1680°C, suitable for prolonged high-temperature melting processes .

5.Low Thermal Expansion: Extremely low coefficient of thermal expansion, providing excellent dimensional stability and resistance to thermal deformation .

6.General Laboratory Use: Perfect for gravimetric analysis, sample ashing, and chemical synthesis requiring extreme heat .

7.Customizable Sizes: Available in various shapes (cylindrical, low form) and dimensions, from 5ml to 10,000ml , tailored to specific client requirements .
