Extreme High-Temperature Stability
Engineered from high-purity quartz, these stands can withstand the severe temperatures inside electrolysis furnaces (far exceeding typical glass), ensuring structural integrity and reliable performance without deformation or degradation in continuous high-heat operations.
Superior Corrosion Resistance
Quartz offers exceptional resistance to a wide array of corrosive agents, including molten salts, acids, and aggressive chemicals common in electrolysis processes. This prevents chemical attack, ensuring long product life and preventing contamination of the electrolytic bath or products.
High Purity & Non-Contaminating
Made from ultra-high purity fused silica, these positioning stands do not introduce impurities into sensitive electrolytic processes, which is crucial for applications requiring high-purity metal deposition, chemical synthesis, or material analysis.
Precise Positioning & Customization
Designed for exact placement, these stands provide stable and reliable support for crucibles, electrodes, or samples within the furnace. Their ability to be custom-fabricated to specific dimensions, shapes, and load-bearing requirements ensures a perfect fit for diverse electrolysis furnace designs and specialized industrial applications.
Application Scenario
Molten Salt Electrolysis
Essential for securely positioning and supporting crucibles, electrodes, or reaction vessels within high-temperature molten salt electrolysis furnaces, where the quartz’s extreme heat and corrosion resistance are critical for safe and efficient operation.
High-Temperature Chemical Vapor Deposition (CVD) & Processing
Utilized as precision supports or fixtures inside CVD reactors and other high-temperature processing furnaces where a non-reactive, stable platform is required to hold substrates or precursor materials, ensuring product purity and process integrity.
Metallurgical Refining & Specialty Metal Production
Employed in furnaces for the refining of specialty metals or the production of high-purity alloys, where the quartz stand supports ingots, crucibles, or other components that are exposed to high temperatures and potentially reactive molten metals or slags.
Laboratory & Industrial Research Furnaces
Provides stable and inert support for samples, reaction vessels, or experimental setups within research furnaces used for materials science, high-temperature chemistry, or advanced ceramics development, especially when purity and resistance to corrosive atmospheres are paramount.
Handle with care
Quartz glass products are made from valuable materials and must be handled gently to avoid collisions and falls.
Regular maintenance
The maintenance of quartz tubes must be performed regularly to ensure their long-term stable performance. Regularly check the connections, fixings, and mechanical vibrations of the quartz tubes to prevent abnormalities. The exterior of the quartz tubes is prone to contamination from dust and moisture, so they should be cleaned regularly.
Storage environmen
When storing quartz tubes, care should be taken to avoid exposure to mechanical vibrations, shocks, and excessively high temperatures. They should be kept in a dry, cool, and well-ventilated place, avoiding direct sunlight and high-temperature environments.
Quartz is preferred due to its unparalleled combination of properties in such extreme environments. It offers exceptional purity, preventing contamination of electrolytic processes; remarkable resistance to extremely high temperatures (often exceeding 1000°C) and thermal shock; and superior chemical inertness against a wide range of corrosive molten salts and acids found in electrolysis, unlike many ceramics or metals that would degrade or react.
Absolutely. We specialize in custom fabrication. Given the varied designs of electrolysis furnaces and specific process requirements, our quartz positioning stands can be precisely customized in terms of dimensions, shape, leg configuration, and even specialized interfaces to securely hold specific crucibles, electrodes, or other components. Please provide your technical drawings or specifications for a tailored solution.
The lifespan of a quartz positioning stand depends on the specific operating conditions, including peak temperatures, thermal cycling frequency, and the corrosivity of the molten bath or atmosphere. However, due to quartz’s inherent durability and resistance to degradation in such environments, these stands typically offer a significantly longer service life compared to alternative materials, reducing downtime and replacement costs. Regular inspection is recommended to assess wear and tear.
