Its core design consists of a vertical tubular furnace chamber. Materials are fed freely through a top-loading device in the form of drops or granules. During their descent, they come into contact with the high-temperature airflow or the furnace walls, resulting in rapid heating, reaction, or pyrolysis. Its typical structure includes:<\/p>\n\n\n\n<p>Vertical furnace tubes: Typically constructed of high-temperature-resistant materials (such as alumina or quartz), with an inner diameter designed based on the processing capacity, typically ranging from 50 to 150 mm.<\/p>\n\n\n\n<p>Heating system: Typically heated by resistance wire or silicon carbon rods, with temperature uniformity achieved through segmented temperature control.<\/p>\n\n\n\n<p>Material conveying device: A hopper feeder or liquid atomizer nozzle is located at the top, with a collection device at the bottom.<\/p>\n\n\n\n<p>Atmosphere control module: Supports the introduction of inert gas, reactive gas, or vacuum to meet oxidizing, reducing, or inert environment requirements.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1300\" height=\"600\" src=\"https:\/\/yexintech.com\/wp-content\/uploads\/2025\/08\/DROP-TUBE-FURNACE.webp\" alt=\"drop tube furnace\" class=\"wp-image-2157\" style=\"object-fit:cover;width:1300px;height:600px\" srcset=\"https:\/\/yexintech.com\/wp-content\/uploads\/2025\/08\/DROP-TUBE-FURNACE.webp 1300w, https:\/\/yexintech.com\/wp-content\/uploads\/2025\/08\/DROP-TUBE-FURNACE-300x138.webp 300w, https:\/\/yexintech.com\/wp-content\/uploads\/2025\/08\/DROP-TUBE-FURNACE-1024x473.webp 1024w, https:\/\/yexintech.com\/wp-content\/uploads\/2025\/08\/DROP-TUBE-FURNACE-768x354.webp 768w, https:\/\/yexintech.com\/wp-content\/uploads\/2025\/08\/DROP-TUBE-FURNACE-18x8.webp 18w\" sizes=\"auto, (max-width: 1300px) 100vw, 1300px\" \/><\/figure>\n\n\n\n<p><br>Key Features of a Drop-Tube Furnace<\/p>\n\n\n\n<p><\/p>\n\n\n\n<p>Rapid Thermal Response: The material residence time in the furnace is short (typically seconds to minutes), making it suitable for studying transient high-temperature reactions (such as pyrolysis and sintering).<\/p>\n\n\n\n<p>Continuous Processing Capability: Continuous feeding and discharging enable batch production and improve efficiency.<\/p>\n\n\n\n<p>Precise Parameter Control: Key parameters such as temperature (room temperature to 1800\u00b0C), atmosphere composition, and material drop velocity can be controlled.<\/p>\n\n\n\n<p>Wide Material Adaptability: Suitable for a variety of material forms, including powders, granules, and droplets, and particularly suitable for dispersing easily agglomerated materials.<\/p>\n\n\n\n<p>Typical Applications:<\/p>\n\n\n\n<p>Materials Science Research<\/p>\n\n\n\n<p>Nano-Powder Synthesis: For example, rapid sintering of ceramic nanoparticles and metal oxide powders.<\/p>\n\n\n\n<p>Studying Material Pyrolysis Behavior: Simulating the decomposition pathways and product properties of materials under high-temperature environments.<\/p>\n\n\n\n<p>Energy and Environmental Protection:<\/p>\n\n\n\n<p>Biomass Pyrolysis: Converting biomass pellets into biochar or bio-oil.<\/p>\n\n\n\n<p>Catalyst Regeneration: Restoring catalyst activity through high-temperature treatment, such as in the regeneration of automotive exhaust catalysts.<\/p>\n\n\n\n<p>Metallurgy and Chemical Industry<\/p>\n\n\n\n<p>Metal Powder Preparation: Atomizing metal salt solutions and then pyrolyzing and reducing them to ultrafine metal powders.<\/p>\n\n\n\n<p>Scrap Material Recycling: For example, high-temperature separation and purification of metals from electronic waste.<\/p>\n\n\n\n<p>Semiconductor and Electronic Materials<\/p>\n\n\n\n<p>Thin Film Precursor Synthesis: High-purity compound powders required for the preparation of semiconductor thin films.<\/p>\n\n\n\n<p>Ceramic Coating Preparation: Forming ceramic coatings on substrate surfaces through the pyrolysis reaction of vapor deposition precursors.<br>Advantages Compared to Other Tube Furnaces<\/p>\n\n\n\n<p>Comparison Items: Drop Tube Furnace, Horizontal Rotating Tube Furnace, Vertical Static Tube Furnace<\/p>\n\n\n\n<p>Material Flow Mode: Free Fall (Short Contact), Rotating Tumble (Continuous Contact), Static Position (Fixed Position Heating)<\/p>\n\n\n\n<p>Processing Efficiency: Continuous batch processing, suitable for large-scale production;
