Uniform Gas Distribution in High-Temperature Furnaces
Designed with precision-engineered perforated structures, these quartz diffusers ensure an even and consistent flow of gases within furnace tubes, preventing gas channeling and optimizing process efficiency in high-temperature applications.
Exceptional High-Temperature & Chemical Resistance
Made from high-purity fused silica, these diffusers can withstand the extreme temperatures and harsh chemical environments commonly found inside industrial and laboratory furnaces, ensuring long service life and stable performance.
High Purity for Contamination-Sensitive Processes
The inherent high purity of quartz minimizes the introduction of impurities into the process gas or reaction environment, which is crucial for sensitive applications such as semiconductor manufacturing, material synthesis, and high-purity annealing.
Customizable for Diverse Furnace Tube Sizes & Applications
Available and customizable for a wide range of furnace tube diameters (e.g., 50mm to 250mm), these diffusers can be specifically tailored in terms of length, hole pattern, and mounting to perfectly fit various furnace designs and meet unique process requirements.
Application Scenario
Semiconductor Manufacturing (Diffusion & CVD)
Crucial for processes like doping, diffusion, and Chemical Vapor Deposition (CVD) within semiconductor furnaces. They ensure the precise and uniform delivery of process gases across silicon wafers, which is critical for achieving consistent film thickness and material properties.
High-Temperature Annealing & Heat Treatment
Employed in furnaces for annealing, sintering, or other heat treatment processes where a precisely controlled and uniformly distributed atmospheric gas (e.g., inert gas, reducing gas, or oxidizing gas) is required to achieve desired material properties.
Catalysis Research & Reactor Systems
Used in laboratory and pilot-scale catalytic reactors or packed bed systems to ensure the even distribution of reactant gases over catalyst beds, optimizing contact efficiency and reaction yield, especially under high-temperature conditions.
Advanced Material Synthesis
Essential for synthesizing advanced materials that require specific gas atmospheres at elevated temperatures, such as in the production of specialty ceramics, composite materials, or in processes where uniform gas flow prevents localized hot spots or undesirable side reactions.
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.
A quartz gas diffuser significantly improves the process by ensuring uniform distribution of gas throughout the furnace tube. This prevents gas channeling, hot spots, and uneven reactions, leading to more consistent and repeatable results, better material properties, and optimized use of process gases in high-temperature applications.
Our quartz gas diffusers are designed to fit a wide range of standard furnace tube diameters, commonly from 50mm up to 250mm, as indicated by the product specifications. Yes, customization is a key offering; we can fabricate diffusers with specific lengths, internal structures, hole patterns, and mounting configurations to precisely match your unique furnace dimensions and process requirements.
Due to their high-purity fused silica construction, these quartz gas diffusers are highly inert and can effectively diffuse a wide variety of process gases, including inert gases (e.g., argon, nitrogen), reactive gases, and corrosive gases (except hydrofluoric acid and hot phosphoric acid) without degrading or contaminating the gas stream. They are designed for use in high-temperature furnace environments, typically operating stably at temperatures up to 1200°C.
