The 1950 ℃ aluminum nitride vacuum sintering furnace is the core equipment that meets the ultra-high temperature sintering requirements of aluminum nitride ceramics. It needs to have a high vacuum system, efficient heating elements, anti pollution design, and stress control functions. It is recommended to choose KJ Technology's supplier products with technical strength. The following is a detailed introduction to the device:
1. Core functions of the device
Vacuum sintering environment: Aluminum nitride materials are prone to react with oxygen, water vapor, etc. at high temperatures, leading to performance degradation. The vacuum sintering furnace creates a high vacuum environment (with a maximum vacuum degree of 10-4Pa or below), effectively avoiding material oxidation and ensuring product purity.
Ultra high temperature processing capability: The sintering of aluminum nitride ceramics needs to be completed in an ultra-high temperature environment of 1800-1900 ℃, and the equipment needs to maintain this temperature range stably to ensure complete densification of the material, obtaining excellent thermal conductivity, mechanical strength, and insulation stability.
Multi process compatibility: Supports multiple processes such as vacuum sintering, negative pressure debinding sintering, and carrier gas debinding sintering. An integrated debinding system can be optionally selected to achieve one-time completion of ceramic green body debinding and high-temperature sintering, shortening the production cycle and reducing intermediate pollution.
2. Technical characteristics of equipment
High vacuum system: Adopting an efficient sealing structure and multi-stage vacuum pumping device, it quickly creates an ultra-high cleanliness sintering environment, timely discharges volatile substances generated during the process, and clears obstacles for powder densification.
Efficient heating system: High temperature resistant and anti-oxidation high-quality heating elements (such as graphite heating elements) are selected, combined with multi zone independent temperature control and heat field homogenization design, to accurately control the heating rate, insulation temperature, and temperature distribution inside the furnace, adapting to the needs of different particle sizes and formulations of aluminum nitride materials.
Anti pollution structure: The inner wall of the furnace is made of special materials that are high-purity, corrosion-resistant, and do not react with aluminum nitride, avoiding material pollution at high temperatures from the source and ensuring product cleanliness and stable performance.
Stress control system: The flexible insulation layer and adaptive support structure effectively alleviate the thermal stress caused by temperature gradients, ensuring that the powder body maintains stable morphology during sintering and avoiding problems such as cracking and deformation.
3. Equipment application field
In the field of electronic packaging, it is used to produce core components such as high thermal conductivity aluminum nitride ceramic substrates and electronic packaging shells. It quickly conducts the heat generated during the operation of electronic devices, ensures stable operation of devices under high temperature conditions, and helps electronic devices develop towards high power and miniaturization.
High end ceramic field: As a high-temperature and corrosion-resistant aluminum nitride structural ceramic production equipment, it is widely used in industrial kiln lining, precision mechanical components and other scenarios, significantly extending the service life of products.
In the field of new energy, the production of insulation and heat dissipation components suitable for power modules and energy storage equipment of new energy vehicles can solve the heat dissipation problem of new energy equipment and improve equipment operation efficiency and safety with efficient thermal conductivity and insulation performance.
In the aerospace field, it is used for the production of thermal protection materials for spacecraft and packaging components for satellite electronic equipment. It can maintain stable performance in complex environments such as extreme temperatures and vacuum, providing protection for space missions.
4. Equipment selection suggestions
Focus on technical strength: Choose suppliers with deep expertise in the field of special thermal equipment and experience in the research and production of aluminum nitride vacuum sintering furnaces, such as KJ Technology, whose product technology is mature, performance is stable, and can better meet process requirements.
Testing equipment parameters: Based on our own process requirements, we focus on core parameters such as the maximum temperature, temperature uniformity, and ultimate vacuum degree of the equipment to ensure that it can stably maintain the 1800-1900 ℃ ultra-high temperature environment required for aluminum nitride sintering, and that the temperature uniformity meets production standards.
Evaluate process compatibility: Prioritize equipment that supports multiple sintering processes and has integrated degreasing systems to improve production flexibility, shorten production cycles, and reduce production costs.
Understand after-sales service: Choose a supplier that can provide comprehensive after-sales service to ensure that the equipment can receive timely technical support and maintenance during use, reducing the risk of production interruption caused by equipment failure.
