Fully transparent high-purity quartz crucible for laboratory-Mia

Different from the double-layer milky white arc crucible used in photovoltaic crystal pulling, this product is made by integrating a whole piece of high-purity transparent quartz glass through one-step hot forming. There are no bubble layers, and the inner wall is polished with fire. It combines high light transmittance and extremely high cleanliness, filling the gap in high-purity quartz heat container solutions for laboratories, material research, and photochemical reaction scenarios.

The transparent quartz crucible has a high SiO₂ purity and strict control of metal impurities, with extremely low evaporation at high temperatures, preventing sample contamination. It has an extremely low thermal expansion coefficient, excellent thermal shock resistance, and a long-term use temperature of up to 1100°C, with a short-term maximum tolerance of 1250°C. It is resistant to most strong acids and oxidants. The overall high transparency feature allows for direct observation of the internal melting, crystallization, and reaction states, and its excellent ultraviolet transmission is suitable for photo-thermal coupling experiments and ultraviolet high-temperature reaction systems.

The product is mainly for medium and small-sized specifications, with optional crucible covers, and supports custom orders based on drawings: closed-end type, straight tube type, with a flow guide nozzle, thick-walled type, and non-standard irregular shapes. All can be processed. Factory inspection is conducted for each piece, strictly controlling scratches, stones, bubbles, and spots. Tempering is used to eliminate internal stress, reducing the risk of cracking due to rapid cooling and heating.

Main applications: geological ore melting samples, ICP / elemental analysis pre-treatment, material sintering, fluorescent powder firing, photochemical reactions, small-sized special crystal cultivation, university and research institute physical and chemical experiments. It is not suitable for large-sized photovoltaic single crystal long-term crystal pulling (the mainstream photovoltaic production is the milky white heat insulation crucible).
