Exceptional Durability & Thermal Stability
Engineered with robust, flawless fused construction, these quartz boats exhibit outstanding resistance to high temperatures (up to 1200°C continuous use) and severe thermal shock. This resilience guarantees a long service life, significantly reducing replacement costs and downtime in demanding industrial and research environments.
Unwavering Purity & Contamination Control
Fabricated from ultra-high purity fused quartz, these boats are inherently non-contaminating, preventing the leaching of impurities or reactions with sensitive samples even at extreme temperatures. This is vital for maintaining the integrity of semiconductor wafers, high-performance materials, and analytical samples, ensuring reliable and accurate results.
Optimized Design for Tube Furnaces & Batch Processing
The rectangular shape is specifically designed to maximize sample loading capacity and ensure uniform heating within cylindrical tube furnaces, unlike round crucibles. This efficiency is critical for batch processes in semiconductor manufacturing, material annealing, and other high-volume thermal treatments.
Precision Handling with Securely Fused Features
Each boat features a smooth, polished surface for easy sample loading and removal, along with securely fused handles (or lugs) for safe and stable insertion and extraction from hot furnaces. This ergonomic design minimizes accidental spills and ensures operator safety during critical high-temperature transfers.
Application Scenario
Semiconductor Wafer Processing (Oxidation, Diffusion, Annealing)
These boats are critical components within tube furnaces in semiconductor fabrication. They are precisely designed to carry multiple silicon wafers or other semiconductor substrates, ensuring even gas flow and temperature distribution during processes like oxidation, dopant diffusion, or post-implantation annealing. Their high purity prevents contamination of the sensitive device layers.
Material Sintering & Heat Treatment in Tube Furnaces
Used extensively in materials science for the high-temperature treatment of powders, ceramics, or small metallic components. Researchers place their samples in these rectangular boats within a tube furnace to achieve specific material properties through sintering, crystal growth, or various annealing processes, where precise temperature control and an inert environment are essential.
Combustion & Ashing Analysis of Solid Samples
In analytical laboratories, particularly for elemental analysis or quality control in industries like coal, plastics, or environmental, these boats serve as sample carriers for high-temperature combustion or ashing processes. They reliably contain solid samples while being heated in furnaces to determine ash content, volatile matter, or prepare samples for further elemental analysis.
Vacuum Deposition (PVD/CVD) Substrate Carriers
Within vacuum coating systems, these rectangular boats can function as substrate carriers or source material holders for physical vapor deposition (PVD) or chemical vapor deposition (CVD). They provide a stable, high-purity platform for heating substrates to achieve uniform film growth or for containing source materials that need to be evaporated or sublimated under vacuum conditions.
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.
Yes, absolutely. Customization is a core service for our quartz rectangular boats. We understand that tube furnace inner diameters, sample sizes, and process needs vary significantly. We can tailor the boat’s length, width, height, wall thickness, bottom profile (flat or rounded ends), and even add internal dividers or specific handle designs to ensure a perfect fit and optimal performance for your unique application. Please provide your exact specifications or a technical drawing for a custom quote.
For safe and efficient operation, we recommend using appropriate quartz or ceramic push rods or long tongs that are designed to handle high-temperature labware. The fused ring handles (or lugs) on our boats are specifically designed to provide a secure point of contact for these tools, minimizing the risk of dropping or damaging the boat and its contents. It’s crucial to ensure a smooth, controlled insertion and withdrawal to prevent thermal shock to the boat or damage to the furnace tube.
To maintain the high purity and extended lifespan of your quartz boats, regular cleaning is essential. For general use, rinse thoroughly with deionized water. For stubborn residues, soaking in a dilute acid solution (excluding hydrofluoric acid) is often effective, followed by a final rinse with ultra-pure water. Always avoid abrasive scrubbing materials that can scratch the polished surface, as these scratches can compromise purity and weaken the quartz over time. Store them in a clean, dust-free environment when not in use.
