hydrothermal synthesis autoclave reactor

hydrothermal synthesis autoclave reactor is a high-pressure laboratory vessel designed for performing chemical reactions under high temperature and high pressure conditions. It is widely used for crystal growth, nanomaterial preparation, and chemical synthesis. The autoclave consists of a stainless steel outer shell and a Teflon (PTFE) inner liner, ensuring both durability and chemical resistance.

This dual-layer structure allows scientists to conduct reactions that require extreme conditions, promoting the formation of compounds that are impossible to synthesize under normal atmospheric environments.

Working Principle of Hydrothermal Autoclave Reactor

The hydrothermal synthesis reactor works by sealing a reaction mixture inside the PTFE liner, which is then enclosed within the stainless steel chamber. When heated in an oven or furnace, the internal pressure increases due to solvent vaporization. This creates a hydrothermal environment, allowing controlled crystallization, oxidation, or reduction reactions to occur safely.

Such conditions are essential in nanomaterials research, geochemistry, and chemical material synthesis, where temperature and pressure directly affect particle morphology and crystal structure.

Main Components

Outer Shell: Made of stainless steel (304 or 316), providing strength and heat resistance.
Inner Liner: Constructed from PTFE or PPL material, ensuring chemical inertness.
Sealing Cap and Bolt: Ensures airtight closure and prevents leakage.
Safety Valve (optional): Releases excess pressure for safe operation.

Key Features

High-Temperature Resistance: Typically up to 280°C.
Pressure Endurance: Can safely operate at up to 3 MPa.
Corrosion Resistance: The Teflon liner resists strong acids, alkalis, and solvents.
Excellent Sealing Performance: Prevents leakage and contamination.
Multiple Capacity Options: Available in 25 mL, 50 mL, 100 mL, 200 mL, and 500 mL models.

Applications of Hydrothermal Synthesis Autoclave Reactor

The reactor is essential in various scientific and industrial fields, including:

Nanomaterial Synthesis – TiO₂, ZnO, Fe₃O₄ nanoparticles
Crystal Growth and Ceramic Material Research
Zeolite and Perovskite Material Production
Chemical Catalyst Development
Geological and Mineral Studies

Its versatility makes it a must-have for chemical laboratories, universities, and R&D institutions.

Operating Instructions

Place your sample and solvent into the PTFE liner.
Ensure proper sealing with the stainless-steel cap.
Heat the autoclave in an oven to the desired temperature.
Allow it to cool naturally before opening.
Carefully remove and clean the PTFE liner after each use.

Safety Guidelines

Do not exceed the rated temperature and pressure.
Avoid sudden cooling or opening.
Clean and inspect the liner and gasket regularly.
Keep the reactor in a dry environment after use.
