Quartz crucibles are lab and industrial containers made from high-purity quartz (silicon dioxide, SiO?) used to hold materials at very high temperatures—especially in processes like semiconductor manufacturing, glass production, and metallurgy.
High thermal resistance: Can withstand temps up to ~1,100–1,300°C continuously (even more short-term).
Thermal shock resistance: Great at handling sudden changes in temperature without cracking.
High purity: Ideal for processes that require low contamination (e.g., growing silicon crystals).
Chemical resistance: Inert to most acids (except HF), making them good for harsh environments.
Common Uses:
Growing silicon crystals (Czochralski process in semiconductor industry)
Melting and refining metals
High-temperature chemical reactions in labs
Making specialty glass or ceramics
