I. Product Overview
This product is specially developed for high-temperature industrial furnaces and is made by integrating high-density and high-strength isostatic pressing graphite materials. The core is designed to adapt to the extreme operating environments of vacuum furnaces, sintering furnaces, and single crystal furnaces. Thanks to the excellent properties of the graphite material itself and the precise processing technology, the product can maintain stable mechanical properties and structural integrity even under ultra-high temperatures, rapid temperature changes, vacuum / inert gas atmospheres. It is a core component for high-end material preparation and crystal growth in fields such as crystal growth and material preparation (can be used as graphite trays, supports, crucibles, flow diverters, etc.).
II. Core Product Characteristics (Detailed Explanation)
1. High mechanical strength, outstanding load-bearing and deformation resistance
The high-strength graphite substrate produced by isostatic pressing molding technology has a bending strength of 40-60 MPa at room temperature and a compressive strength of ≥ 120 MPa, far exceeding that of ordinary molded graphite products;
Key advantages: The mechanical strength attenuation rate in high-temperature environments (1500-2500℃) is ≤ 15%, without softening or collapse risks, capable of bearing multiple layers of material stacking loads (single component load-bearing capacity can reach 50-100 kg), suitable for the loading requirements of industrial furnace large-scale production;
Structural stability: After precise processing, the dimensional tolerance is controlled within ±0.01mm, with excellent flatness, and does not warp or deform over the long term, ensuring the accuracy of material placement and the utilization rate of the furnace interior space.
2. Outstanding heat resistance, suitable for extreme high-temperature conditions High-temperature resistance limit: It can stably withstand temperatures above 2800℃, with a short-term peak temperature reaching up to 3000℃. This fully covers the core working temperature ranges of vacuum furnaces (1000-2200℃), sintering furnaces (800-1800℃), and single crystal furnaces (1400-2000℃).
High-temperature characteristics: No melting, no volatilization, no odor, no harmful gases are produced, and no pollution to the atmosphere inside the furnace or the processed materials;
Thermal stability: During long-term high-temperature service, the crystal structure remains stable, without oxidation or peeling (in vacuum / inert gas environments), effectively prolonging the service life of components and the cleaning cycle inside the furnace.
3. Strong thermal shock tolerance, suitable for rapid temperature variation cycles
Core principle: The thermal expansion coefficient of graphite materials is extremely low (1-4×10⁻⁶/℃), only 1/5-1/10 of that of metals, significantly reducing the thermal stress generated by cold and hot cycles;
Actual performance: Can withstand a rapid heating and cooling rate of 50℃/min, without cracking, chipping, or fragmentation during the "room temperature - 1800℃ - room temperature" cycle, with a cycle service life of over 1000 times;
Production value: Suitable for the aggressive temperature variation process of industrial furnaces for continuous production, reducing downtime and component replacement due to damage, and improving production efficiency and continuity.
4. Additional advantages: Chemical stability + strong adaptability
Chemical inertness: Does not react chemically with metal, ceramic, semiconductor materials and other processed materials, without impurity dissolution, ensuring product purity (graphite purity ≥ 99.99%, ash content ≤ 0.01%);
Adaptation to special atmospheres: Performs stably in vacuum, argon, nitrogen and other inert / reducing atmospheres, does not oxidize or corrode, meeting the strict environmental requirements of precision processing;
Easy processing and customization: Can be precisely processed into trays, supports, crucibles, flow channels and other structures according to furnace type specifications and usage scenarios, adapting to the installation and usage requirements of different furnaces.
