Specifications of Cordierite mullite sagger glass melting refractory crucible negative electrode materials saggar

The Cordierite Mullite Sagger Glass Melting Refractory Crucible is engineered for high-temperature applications, especially in handling unfavorable electrode products for lithium-ion batteries. Its structure combines cordierite (2MgO · 2Al ₂ O ₃ · 5SiO ₂)and mullite(3Al ₂ O ₃ · 2SiO ₂), usually with 40-50% alumina, 30-40% silica, and 10-15% magnesia. This mix ensures exceptional thermal shock resistance, mechanical stamina, and chemical security, making it ideal for duplicated heating-cooling cycles. The crucible operates effectively at temperature levels approximately 1350 ° C, with short-term resistance to 1450 ° C, supported by a low thermal development coefficient (1.5– 2.5 x10 ⁻⁶/ ° C )to decrease breaking. Its modest thermal conductivity (1.5– 2.5 W/m · K) ensures uniform warm distribution while saving energy.

Chemically, the product stands up to deterioration from acidic and alkaline atmospheres, crucial for handling reactive electrode elements like graphite or silicon-based compounds. Reduced apparent porosity (15– 20%) reduces infiltration by molten materials, preserving structural integrity. Mechanically, it provides high compressive stamina (50– 70 MPa), ensuring resilience under physical stress during sintering or handling.

Requirement dimensions vary from 200– 500 mm in diameter and 150– 400 mm in elevation, with wall densities of 20– 50 mm. Weight varies between 5– 30 kg, depending upon size. These crucibles are commonly used in battery manufacturing for sintering adverse electrodes, as well as in glass melting, ceramics, and metallurgy.

Benefits over alumina or zirconia crucibles consist of remarkable thermal shock resistance, cost-effectiveness, and expanded life span, decreasing substitute regularity. Manufacturing follows ASTM/ISO criteria, using isostatic pushing and sintering at 1400– 1500 ° C for thickness and homogeneity. Customization in size, shape, or composition is offered to fulfill certain industrial requirements. The Cordierite Mullite Sagger makes sure reliability in high-temperature procedures, integrating performance with financial effectiveness.

Applications of Cordierite mullite sagger glass melting refractory crucible negative electrode materials saggar

Cordierite-mullite sagger glass melting refractory crucibles are specialized ceramic containers developed for high-temperature commercial applications, specifically in the manufacturing of unfavorable electrode products for lithium-ion batteries and glass melting processes. These crucibles combine cordierite and mullite ceramics, providing outstanding thermal shock resistance, chemical security, and mechanical strength. Their special composition makes certain durability in severe environments, making them perfect for sintering, calcination, and warmth therapy of sensitive materials.

In lithium-ion battery manufacturing, these saggers are crucial for refining adverse electrode products like graphite, silicon, or composite anodes. They withstand temperature levels surpassing 1,300 ° C while maintaining architectural integrity during repeated home heating and cooling cycles. The reduced thermal growth coefficient of cordierite-mullite lessens splitting, ensuring regular performance and longevity. Their chemical inertness avoids contamination of electrode materials, protecting pureness and electrochemical efficiency.

For glass melting, these crucibles withstand destructive interactions with molten glass and high-viscosity slags, making certain marginal product destruction. They are used in kilns and heating systems for melting specialized glasses, fiber optics, and ceramics, where accurate temperature control and contamination-free settings are important.

Extra applications include metallurgy, uncommon earth handling, and progressed porcelains manufacturing. The saggers’ high alumina content boosts refractoriness, while the cordierite part boosts thermal shock resistance. This balance makes them ideal for sectors needing energy-efficient, high-temperature options with reduced downtime.

Secret advantages consist of expanded life span, reduced functional prices due to reduced substitute frequency, and energy efficiency from outstanding thermal management. Their eco-friendly profile straightens with sustainable production practices, as they lessen waste and power intake.

In recap, cordierite-mullite saggers are essential in markets requiring reliability at extreme temperature levels. Their flexibility in managing unfavorable electrode materials, glass melts, and various other high-purity processes highlights their function beforehand power storage space, electronic devices, and material scientific research modern technologies. By combining sturdiness, thermal strength, and chemical security, these crucibles maximize production efficiency and item top quality sought after industrial settings.

5 FAQs of Cordierite mullite sagger glass melting refractory crucible negative electrode materials saggar

What is a Cordierite-Mullite Sagger Crucible, and what is it used for? A Cordierite-Mullite Sagger Crucible is a high-temperature refractory container designed for melting, sintering, or heat-treating materials like glass or lithium battery negative electrode components. It is made from a blend of cordierite and mullite ceramics, offering excellent thermal shock resistance, chemical stability, and mechanical strength. These saggers are commonly used in industrial kilns or furnaces to protect materials from contamination while withstanding extreme temperatures and corrosive environments.

What temperature range can Cordierite-Mullite Saggers withstand? Cordierite-Mullite Saggers typically operate efficiently in temperatures ranging from **1200°C to 1450°C**, depending on the specific composition and manufacturing process. Their low thermal expansion coefficient minimizes cracking under rapid temperature changes, making them ideal for repeated heating and cooling cycles in glass melting or anode material processing.

Why choose Cordierite-Mullite over other refractory materials? Cordierite-Mullite combines the best properties of both minerals: cordierite provides exceptional thermal shock resistance, while mullite enhances high-temperature strength and corrosion resistance. This hybrid material outperforms alternatives like alumina or silicon carbide in applications requiring cyclic heating, reducing downtime and replacement costs. It also resists reactions with molten glass or reactive chemicals in battery materials.

How long does a Cordierite-Mullite Sagger last? Lifespan varies based on operating conditions, but these saggers generally endure **20 to 50 cycles** under optimal use. Factors like peak temperature, cooling rate, and exposure to aggressive materials (e.g., alkali vapors in glass melting) affect durability. Proper handling, gradual heating/cooling, and avoiding mechanical shocks can extend their service life.

How to maintain Cordierite-Mullite Saggers for maximum efficiency? Regular inspection for cracks or warping is critical. Clean residual material after each cycle to prevent chemical interactions. Avoid sudden temperature changes—preheat saggers slowly and allow gradual cooling. Store them in a dry, stable environment to prevent moisture absorption, which can weaken the structure. Replace saggers showing significant wear to avoid contamination of processed materials.
