Four custom-made 1200°C large-capacity 392 liter Chamnber Furnaces have been shipped to Suzhou, Jiangsu Province, mainly for the heat treatment of glass materials.

Chamber furnaces play a vital role in glass material preparation and processing, primarily serving the following critical functions:
 1. Melting and clarifying glass materials
 Raw Material Melting: Heating batch materials (quartz sand, soda ash, limestone, etc.) in a chamber furnace to high temperatures (typically 1200-1500°C) to transform them into a uniform glass melt.
 Clarification and homogenization: Eliminating bubbles and streaks at high temperatures to achieve a defect-free glass melt with uniform composition.

 2. Annealing of glass products
 Stress Relief: Post-formed glass products are heated in a chamber furnace to annealing temperatures (e.g., 500–600°C), held at temperature, and then slowly cooled to eliminate internal thermal stresses and prevent breakage.
 Stability Enhancement: Precise control of cooling rates ensures optimal mechanical properties and thermal stability of the glass.

 3. Sintering and Microcrystallization of Glass Materials
 Sintering Forming: Used to prepare specialty glass, microcrystalline glass, or porous glass materials by densifying glass powder through high-temperature sintering.
 Crystallization Control: Heat-treating microcrystalline glass to regulate nucleation and crystal growth, achieving specific properties (e.g., high strength, heat resistance).

 4. Glass Surface Treatment and Modification
 Tempering: Heating glass near its softening point followed by rapid cooling (air quenching) to create a surface compressive stress layer, enhancing strength and impact resistance.
 Coating Sintering: Functional coatings (e.g., conductive films, anti-reflective coatings) are applied to the glass surface and thermally treated to achieve strong adhesion or specific chemical reactions.

 5. Specialty Glass Preparation
 Doping and Coloring: Incorporating metal ions (e.g., cobalt, chromium) into glass via high-temperature diffusion in a chamber furnace to achieve coloring or functional modification.
 Sealing Process: Used for bonding glass to metal or ceramic substrates. Heating softens the glass to form an airtight seal with the material.

 6. Experimental Research and Development
 Composition Testing: Evaluates melting characteristics and crystallization behavior of various glass formulations in small-scale chamber furnaces.
 Process Optimization: Determining optimal heat treatment parameters (temperature, time, atmosphere) for industrial production.

 Chamber furnaces offer the following technical features and advantages
 1. Temperature Uniformity: Chamber furnaces typically offer excellent temperature uniformity, suitable for uniform glass heating.
 2. Atmosphere Control: Some chamber furnaces allow the introduction of protective gases (e.g., nitrogen) to prevent surface oxidation or volatilization of glass components.
 3. Operational Simplicity: Suitable for laboratory use, small-batch production, or processing complex-shaped workpieces.
