High temperature resistant microcrystalline glass ceramic

---

High temperature resistant microcrystalline glass ceramic, also known as microcrystalline glass, is an advanced composite material that combines crystalline phase and glass through high-temperature melting, precision molding, and controlled crystallization heat treatment. It not only perfectly inherits the dense and pore free properties of glass and the high strength of ceramics, but also has an extremely low coefficient of thermal expansion and excellent thermal shock resistance. It is a high-performance industrial material designed to cope with extreme high temperatures and complex working conditions.

Faced with the harsh environment in industrial production, this material mainly solves the following core problems for you:
Extreme temperature difference challenge: Able to maintain stable properties even in high temperature environments ranging from 800 ℃ to 1000 ℃, or through intense alternation of heat and cold, completely bidding farewell to the explosion and deformation problems of traditional glass or metal materials.
High strength wear and corrosion: Under the continuous impact of acidic and alkaline corrosive media or heavy materials, it provides far superior wear and corrosion resistance protection than ordinary steel and ceramics, greatly extending the service life of equipment.
Precision machining and insulation requirements: Meeting high-precision mechanical machining requirements while possessing excellent electrical insulation and vacuum performance, it is an ideal substrate for high-end electronics and precision instruments.

Advantages and Application Value
High temperature resistant microcrystalline glass ceramics, with their comprehensive performance resembling a hexagonal warrior, have demonstrated irreplaceable value in many industrial fields
Excellent high temperature resistance and thermal shock resistance: This material can withstand temperatures up to 800 ℃~1000 ℃ and has an extremely low coefficient of thermal expansion (0~15 × 10 ⁻⁷/℃). Even after being insulated at 700 ℃ and subjected to air cooling or severe thermal shock testing, it can still maintain dimensional stability and no crack precipitation, making it very suitable for scenarios such as high-temperature sintering furnace observation windows and rocket engine insulation components.
Extremely high mechanical strength and wear resistance: Through precise process control, its bulk density can reach over 3.6g/cm ³, bending strength can reach 220-250MPa, and compressive strength can reach 1300MPa. The dense microstructure makes its water absorption rate extremely low (≤ 0.01%), which can effectively resist the continuous impact and wear of heavy materials.
Excellent electrical insulation and chemical stability: As an excellent high-temperature electrical insulation material, it has extremely high volume resistance and low dielectric loss. At the same time, it has strong corrosion resistance to various acids, bases, and organic solvents, and is non-magnetic and non aging. It performs extremely well in vacuum devices such as chemical equipment liners and electron beam exposure machines.

Customer application case sharing
Case 1: Preheater Inner Cylinder Renovation Project of a Large Cement Enterprise
The customer has long faced the problem of short service life and frequent kiln shutdown for maintenance of the preheater inner cylinder under high temperature and material erosion. After introducing our high-temperature resistant microcrystalline wear-resistant ceramic lining plate to replace traditional heat-resistant steel hanging plates, the equipment still maintains extremely high stability in high-temperature environments below 1200 ℃. After long-term operation monitoring, the service life of the inner cylinder has been significantly extended from the original 8-10 months to 2-3 years. The occurrence of detachment accidents caused by high-temperature creep has been reduced by more than 90%, significantly reducing customers’ kiln maintenance costs and production losses.
Case 2: Procurement of Insulation Supports by a Precision Instrument Manufacturing Enterprise
When developing a new mass spectrometer, the customer requires an insulation material that can withstand high temperature vacuum environments and perform precise machining of complex thin-walled structures. We have customized a specific specification of microcrystalline glass ceramic bracket for it. This material not only meets the dimensional stability requirements of customers in a wide temperature range of -270 ℃ to+800 ℃, but also has excellent vacuum performance (with a low gas release rate of 8.8 × 10 ⁻⁹ ml/s · cm ²) and high electrical insulation strength, perfectly ensuring the precise operation of the instrument and helping customers significantly shorten the development cycle.
