95 alumina ceramic crucible round cover

The 95 alumina ceramic crucible round cover is a precision ceramic component designed specifically for harsh high-temperature environments. With its excellent high temperature resistance, thermal shock resistance, and chemical stability, it has become an ideal choice in the fields of metallurgy, materials science, electronics, and laboratory research.

Product core advantage: Why is 95 alumina ceramic the top choice?
95% alumina ceramic (with Al ₂ O3 content ≥ 95%) is a high-performance industrial ceramic, and the crucible round cover made from it has the following unparalleled advantages:

1. Excellent high temperature resistance: The maximum operating temperature can reach 1650 ℃ or above, and the stability of shape and strength can still be maintained in long-term high temperature environments, effectively preventing softening and deformation.
2. Excellent thermal shock resistance: able to withstand sudden temperature changes (rapid cooling and heating), not easy to crack, greatly extending the service life of the product and reducing the cost of frequent replacement.
3. Excellent chemical inertness: It has excellent resistance to most acids, bases, salts, and molten metals, ensuring that samples are not contaminated during experiments or production processes, and guaranteeing the purity and accuracy of results.
4. High mechanical strength and hardness: The structure is sturdy, wear-resistant and pressure resistant, capable of withstanding certain physical impacts and mechanical stresses, and performs well in frequent use and handling.
5. Low thermal conductivity and excellent insulation: As a good thermal and electrical insulator, it helps to evenly distribute the temperature inside the furnace and ensures operational safety.

Main application areas
95 alumina ceramic crucible round cover is an indispensable accessory in multiple high-tech and industrial fields:
Materials Science and R&D: Used for sintering, synthesis, and heat treatment of new materials such as positive and negative electrode materials for lithium batteries, phosphors, and ceramic powders.
Metallurgy and Casting: Covering metal or alloy melting crucibles to reduce oxidation and maintain melt composition.
Electronic components: Provide a pure protective environment during the sintering process of semiconductor wafers and electronic ceramic components.
Chemical Analysis Laboratory: As a container lid for high-temperature digestion, ashing, and melting experiments, it prevents sample splashing and cross contamination.
Universities and research institutions: widely used in various high-temperature furnace (such as muffle furnace, box furnace, tube furnace) supporting experiments.

What key issues can we solve?
By choosing our 95 alumina ceramic crucible round cover, you will effectively solve the following common pain points:
Addressing pollution issues: To prevent sample contamination caused by impurities precipitating from the cover material at high temperatures, ensuring the accuracy of experimental data and high purity of the product.
Solving the problem of short lifespan: Say goodbye to the problem of easy cracking and wear of ordinary ceramic covers. Our products have a longer lifespan and lower total cost of ownership.
Addressing the issue of low thermal efficiency: Excellent insulation performance helps improve furnace temperature uniformity, shorten process time, and save energy.
Addressing safety concerns: High strength and thermal shock resistance effectively prevent production interruptions and safety accidents caused by lid rupture.
