Low expansion microcrystalline glass ceramic plate

---

Low expansion microcrystalline glass ceramic plate is a high-performance composite material made based on lithium aluminum silicon (LAS) system and subjected to strict controlled crystallization treatment. It is uniformly distributed with nanoscale β – quartz solid solution crystal phase and positive expansion glass phase inside, endowing the material with extremely low or even close to zero thermal expansion coefficient in a wide temperature range, while also possessing excellent optical transparency, high temperature resistance and thermal shock resistance, making it an ideal substrate in the field of precision manufacturing.

Addressing core user needs and challenges
In extreme temperature changes or high-precision working environments, traditional materials are prone to deformation due to thermal expansion and contraction, which can lead to problems such as dimensional misalignment or structural failure. Low expansion microcrystalline glass ceramic plates are specifically designed to address such challenges, ensuring excellent dimensional stability of equipment under severe temperature differences and effectively eliminating accuracy deviations caused by thermal stress. Whether it is precision instruments that pursue ultimate optical performance or industrial components that need to withstand high temperature impacts, this product can provide you with reliable solutions, significantly reducing maintenance costs and improving the overall system’s operating life.

Advantages and customized specification services
As a new generation of high-performance basic materials, the core value of low expansion microcrystalline glass ceramic panels lies in their irreplaceable physical and chemical stability. Its thermal expansion coefficient can be as low as 10 ⁻⁸/℃, coupled with a temperature resistance upper limit of up to 950 ℃ and extremely low stress birefringence index, making it outstanding in cutting-edge fields such as aerospace, semiconductor lithography, and large astronomical telescopes. In addition, the material has excellent acid and alkali corrosion resistance and high mechanical strength, which can easily cope with complex and harsh working environments.

To meet the personalized research and production needs of different users, we provide comprehensive specification customization services. Whether you need large aperture astronomical telescope mirror blanks, irregularly cut laser gyro resonant cavities, or semiconductor carrier substrates of specific thickness, we can accurately process them according to the drawings. We can provide flexible production solutions from millimeter level precision small parts to meter level large plates, ensuring that every delivered microcrystalline glass ceramic plate perfectly meets your equipment assembly standards.

Typical application cases and reasons for choosing us
Impact resistance testing of heat-resistant rock slabs for high-end commercial kitchens
In the field of high-end civilian home furnishings, traditional ceramic or glass dining table tops and induction cooker panels are prone to cracking or even exploding due to internal stress concentration when subjected to alternating cold and hot conditions (such as a hot pot coming into direct contact with a cold tabletop). A certain ceramic group urgently needs a new type of substrate that can withstand cold and hot cycles above 250 ℃ when developing a new generation of heat-resistant ceramic rock plates for dining tables. After adopting our low expansion microcrystalline glass technology system, the product has performed excellently in the rigorous testing of authoritative institutions: not only has it successfully passed multiple cold and hot cycle tests of tin solution (20-250 ℃) without any cracks on the surface, but its strength attenuation is also controlled within 5%. This breakthrough completely solves the problem of fragile high-end kitchen and bathroom countertops, greatly expanding the application boundaries of ceramic rock panels in smart homes.
