Ceramic fiber shaped products are made from a mixture of refractory fibers through vacuum forming, offering superior high-temperature performance and self-supporting strength. The products exhibit low shrinkage within their operating temperature range and maintain high thermal insulation, lightweight, and resistance to thermal shock. Unburned shaped products can be easily cut or machined. During use, the products demonstrate excellent wear resistance and resistance to spalling, and are not corroded by most molten metals. Our ceramic fiber shaped products come in various sizes and shapes, including tubular, conical, domed, and square box shapes, and can be produced according to customer requirements, with options for surface hardening or complete hardening as needed.
High-temperature furnaces rely on refractory materials and specific manufacturing techniques to determine their maximum operating temperatures. Ceramic fiber materials typically operate up to around 1750 degrees Celsius, although they can withstand up to 1800 degrees Celsius, ensuring stable performance in practical applications. Foam ceramics, designed for temperatures as high as 1800 degrees Celsius, offer excellent thermal insulation and resistance to thermal shock in high-temperature environments. Selecting the appropriate refractory material is essential to ensure safe and efficient operation of high-temperature furnaces across diverse industrial and scientific applications.
High-temperature furnaces are essential components made from various refractory materials. Examples include high-alumina brick furnaces, ceramic fiber furnaces, and foam ceramic furnaces, each serving distinct purposes due to their unique properties. High-alumina brick furnaces, crafted from high-purity alumina oxide, boast excellent resistance to high temperatures and chemical stability, ideal for industrial processes such as metal smelting and heat treatment. Ceramic fiber furnaces, made from high-temperature refractory ceramic fibers, are lightweight with low thermal conductivity, suitable for applications requiring rapid heating and cooling cycles and energy efficiency, such as laboratory sintering and ceramic firing. Foam ceramic furnaces utilize low-density, high-porosity foam ceramic materials, offering superior thermal insulation and thermal shock resistance. They are often used as insulation materials for high-temperature crucible supports and in heat treatment processes. Choosing the appropriate high-temperature furnace material is crucial to ensure stability, safety, and efficiency in high-temperature environments based on specific application requirements.
Crucibles and evaporating dishes, as vessels used for high-temperature experiments and material processing, depend on the material type and manufacturing process for their heat resistance capabilities. Generally, fused quartz crucibles and alumina ceramic crucibles can withstand temperatures of over 1300 degrees Celsius, suitable for various high-temperature melting and chemical reactions. Graphite crucibles, known for their high heat resistance, can withstand temperatures up to 2500 degrees Celsius and are commonly used in experiments and processes requiring extremely high temperatures. Metal crucibles, depending on the specific metal type, have varying temperature resistance ranges and are used for specific high-temperature treatments and alloy melting. Evaporating dishes exhibit similar high-temperature stability in experiments and specialized treatments. When choosing, consideration of the material's heat resistance and chemical properties is crucial to ensure the vessel can safely and reliably withstand the required high-temperature environments.
Crucibles and saggars are containers used for high-temperature chemical reactions or metal melting, categorized into various types based on application requirements and material selection. Crucibles include porcelain crucibles, graphite crucibles, silica crucibles, and alumina crucibles, each suitable for different temperature ranges and chemical environments. Saggars encompass clay saggars, alumina saggars, silicon carbide saggars, and metal saggars, utilized for firing ceramics in kilns, high-temperature ceramic processes, and firing processes in the glass industry. Choosing the appropriate crucible or saggar ensures optimal performance and durability in various high-temperature applications.
A crucible (坩埚) and a saggar (匣钵) are containers used for chemical reactions or melting metals at high temperatures. Typically made from refractory materials such as ceramics or graphite, they possess properties of high temperature resistance and chemical stability. Crucibles are usually round with a wide base and a narrow top, aiding in uniform heating and control of molten materials. Crucibles and saggars are commonly employed in laboratories, industrial production, and metal smelting for high-temperature treatments and chemical reactions.
