Application of Experimental Multi zone Rotary Furnace in the New Materials Industry

The multi temperature zone rotary furnace used in experiments is widely and crucially applied in the new materials industry, especially in the preparation and performance optimization of battery materials, ceramic materials, nanomaterials, and composite materials. It plays an important role, as follows:

1. Preparation and Performance Optimization of Battery Materials
Lithium ion battery materials: Multi temperature zone rotary furnaces can be used for the preparation and performance testing of positive electrode materials (such as ternary materials, lithium iron phosphate) and negative electrode materials (such as graphite, silicon-based materials). By precisely controlling the temperature in different temperature zones, it is possible to simulate the temperature changes of batteries in actual working environments, thereby preparing battery materials with better performance and stronger stability. For example, in an oxygen atmosphere, the use of a multi zone rotary furnace can achieve ordered growth of layered structures of ternary materials, with an initial charge discharge efficiency increased to 92%.
Sodium ion battery materials: Similar to lithium-ion batteries, multi temperature zone rotary furnaces can also be used for the preparation and performance testing of sodium ion battery materials, promoting the development and application of sodium ion battery technology.
Solid electrolyte materials: By utilizing the high-temperature uniformity of a multi zone rotary furnace, the densification of sulfide solid electrolytes can be achieved at high temperatures, reducing interfacial impedance and improving the performance of solid-state batteries.

2. Preparation of Ceramic Materials
High temperature structural ceramics: A multi temperature zone rotary furnace can achieve gradient sintering of ceramic materials such as alumina and silicon carbide, optimize grain growth and densification processes, and improve the mechanical properties and thermal stability of ceramic materials.
Microcrystalline glass: By controlling multiple temperature zones, phase separation and crystallization of microcrystalline glass can be achieved, and microcrystalline glass materials with excellent optical and mechanical properties can be prepared.

3. Nanomaterial synthesis
Chemical Vapor Deposition (CVD): In a multi zone rotary furnace, precise matching of reactant decomposition and deposition can be achieved through zone temperature control, which can prepare high-purity and highly uniform nanomaterials. For example, high-purity polycrystalline silicon with a purity of over 99.9999% can be prepared by reducing SiHCl ∝ in the temperature range of 1100 ℃.
Nanoparticle morphology control: By synergistic effect of rotational motion and temperature gradient, the particle size distribution and morphology of nanoparticles can be optimized. For example, controlling the rotation speed can prepare spherical or sheet-like nano zinc oxide.

4. Preparation of composite materials
Metal based composite materials: A multi temperature zone rotary furnace can be used for the preparation of metal based composite materials. By controlling the temperature and atmosphere in different temperature zones, uniform composite of metal and reinforcing phase can be achieved, improving the mechanical properties and corrosion resistance of composite materials.
Ceramic based composite materials: By utilizing the high-temperature uniformity of a multi zone rotary furnace, the densification and sintering of ceramic based composite materials can be achieved, improving their thermal stability and oxidation resistance.
