1800°C Atmosphere Furnace

Application

Detailed Parameters Of The Product

Equipment introduction:

I. Furnace structure and materials

This equipment is carefully designed and uses high-performance heating materials. Its excellent thermal conductivity allows heat to be transferred quickly and evenly within the furnace, helping to ensure temperature uniformity within the furnace to meet the requirements of different processing processes. The internal structure of the furnace cavity must be spatially designed to consider not only the convenience of placing materials but also the gas flow path to ensure that the atmosphere can fully contact the processed materials and ensure the consistency and uniformity of the atmosphere's effect on the material.

II. High temperature performance

1.High temperature generation and maintenance
High temperature atmosphere furnace achieves high temperature generation and maintenance through an advanced heating system. The heating elements are made of high temperature resistant materials and are reasonably distributed around the furnace, cooperating with the graphite furnace to achieve efficient heat transfer. By precisely controlling the heating power, the temperature in the furnace can be quickly raised to the set high temperature value, and can be stably maintained within the required temperature range during the treatment process, ensuring that the material is processed in a stable high temperature environment.

2.Temperature uniformity
Maintaining excellent temperature uniformity in a high temperature environment is one of the important features of the high temperature atmosphere furnace.This is due to the use of high thermal conductivity heating materials and the optimized design of the heating system, which can achieve higher temperature uniformity.

3. Atmosphere control
The atmosphere furnace can accurately control the atmosphere in the furnace and can adapt to a variety of atmosphere types, including inert atmosphere (such as argon, nitrogen, etc.), reducing atmosphere (such as a mixed atmosphere of hydrogen and inert gas, etc.) and some special process atmospheres.

4.Atmosphere control system
Equipped with a complete atmosphere control system, including a gas supply source, a gas flow controller, a pressure sensor and a gas purification device. The gas supply source provides the required various gases, and the gas flow controller accurately adjusts the gas flow to meet the requirements of different processes for atmosphere concentration. The pressure sensor monitors the pressure in the furnace in real time to ensure that the atmosphere pressure is stable within a safe and appropriate range. The gas purification device purifies the gas entering the furnace to remove impurities such as moisture and oxygen, further improve the purity and quality of the atmosphere, and ensure that the material processing process is not disturbed by impurity gases.

IV. Application Fields

1.Material Science and Engineering
It is widely used in the field of material science, such as sintering of high-temperature ceramic materials (such as silicon nitride, silicon carbide, etc.). During the sintering process, by precisely controlling the temperature and atmosphere, ceramic products with high strength, high hardness and excellent high temperature resistance can be obtained. For the smelting and heat treatment of metal materials, especially some high-melting-point metals (such as tungsten, molybdenum, etc.), this high temperature atmosphere furnace can provide a suitable high temperature and protective atmosphere environment to improve the purity and performance of metal materials. In addition, it also plays an important role in the preparation process of new carbon materials (such as graphene, carbon nanotubes, etc.). By creating a specific atmosphere and high temperature conditions, the growth and structure of carbon materials can be controlled.

2.Electronic Industry
In the electronics industry, it is often used in the preparation and processing of semiconductor materials. For example, in the epitaxial growth process of silicon wafers, high temperature and a specific atmosphere are required. The high temperature atmosphere furnace can meet these requirements and ensure the quality and performance of the epitaxial layer of silicon wafers. For the sintering and processing of some electronic ceramic materials (such as piezoelectric ceramics, dielectric ceramics, etc.), precise temperature and atmosphere control can also be achieved through this furnace to improve the performance and reliability of electronic components.

3.Chemical Industry
In the chemical industry, it can be used for the preparation and activation of catalysts. Many catalysts need to be treated at high temperature and a specific atmosphere to improve their activity and selectivity. The high temperature atmosphere furnace provides ideal conditions for the preparation of catalysts. By controlling the atmosphere and temperature, the surface structure and chemical composition of the catalyst can be adjusted to optimize its catalytic performance. In addition, in the research and production of some high-temperature chemical reactions, it can also be used as a reaction device to provide a stable high temperature and specific atmosphere environment for chemical reactions.
