คุณสมบัติของแบล็คซิลิคอนคาร์ไบด์
ทนต่ออุณหภูมิสูง
Black silicon carbide has an excellent high-temperature resistance, allowing it to withstand temperatures of up to 2730°C (4950°F). This high-temperature resistance makes it suitable for use in furnaces and kilns that operate at extreme temperatures.
การนำความร้อน
Black silicon carbide has high thermal conductivity, which enables it to rapidly dissipate heat. This property is vital in kiln furniture, as it prevents thermal stress and possible cracking or warping of the furniture during firing cycles.
ทนต่อสารเคมี
Black silicon carbide is highly resistant to a wide range of chemicals, รวมถึงกรดและด่าง. This property ensures that it remains stable and does not react with the chemicals used in the kiln environment or with the materials being fired.
ความแข็งแรงทางกล
Black silicon carbide has excellent mechanical strength, which allows it to withstand the stress and weight of the materials placed on the kiln furniture during the firing process.
Applications of Black Silicon Carbide Kiln Furniture
Ceramics and Glass Industries
In the ceramics and glass industries, black silicon carbide kiln furniture is used to support ceramic and glass products during the firing process. This includes the firing of pottery, เครื่องลายคราม, and other ceramic products, as well as the annealing and tempering of glass products.
Metallurgical Industry
Black silicon carbide kiln furniture is used in the metallurgical industry for the firing of metal powders, sintering of metal components, and the heat treatment of metals. Its high-temperature resistance and thermal conductivity make it ideal for these applications.
อุตสาหกรรมเซมิคอนดักเตอร์
ในอุตสาหกรรมเซมิคอนดักเตอร์, black silicon carbide kiln furniture is used in the production of silicon wafers, which are the base material for manufacturing integrated circuits and other electronic devices.
Types of Black Silicon Carbide Kiln Furniture
Kiln Shelves
Kiln shelves are flat, rectangular slabs of black silicon carbide used to support materials during the firing process. They come in various sizes and thicknesses to accommodate different kiln sizes and weight loads.
Kiln Posts
Kiln posts are cylindrical or square supports made from black silicon carbide that elevate the kiln shelves, allowing for proper heat circulation and creating multiple layers within the kiln. They are available in various lengths to accommodate different stacking heights.
Kiln Setters
Kiln setters are specially designed black silicon carbide supports used to hold ceramic and glass pieces in the desired position during the firing process. They come in various shapes and sizes, such as plate setters, ring setters, and stilt setters.
Kiln Supports
Kiln supports are additional black silicon carbide components that provide extra stability and reinforcement to the kiln shelves and posts during firing. They include items such as crossbars and beams.
How to Choose the Right Kiln Furniture
When selecting black silicon carbide kiln furniture, consider factors such as:
- The type of material being fired and its specific requirements.
- The maximum operating temperature of your kiln.
- The size and weight of the materials being fired.
- The desired configuration and arrangement of the kiln furniture.
It’s crucial to choose kiln furniture that can withstand the temperatures and conditions of your specific application while providing adequate support for your materials.
Maintenance and Care of Black Silicon Carbide Kiln Furniture
Proper maintenance and care can extend the life of your black silicon carbide kiln furniture. Follow these tips:
- Clean kiln shelves and other furniture regularly to prevent the buildup of kiln wash, glaze, or other residues.
- Inspect kiln furniture for cracks or damage before each use.
- Avoid rapid heating or cooling cycles, which can cause thermal stress and damage the kiln furniture.
- Store kiln furniture in a clean, ที่แห้งเมื่อไม่ใช้งาน.
- Rotate kiln shelves periodically to ensure even wear and prevent warping.
