Tianyi Quan'an breakthroughs in high-temperature ultra-white reflective coating, achieving 99.9% reflectance in near-to-mid infrared range.

Direct infrared heat only toward the workpiece.

Shanghai — Tianyi Quan'an (Shanghai) Technology Co., Ltd. announced a key breakthrough in high-temperature ultra-white reflective coatings, achieving a reflectivity of 99.9% in the near-infrared and mid-infrared bands. This technology enables precise directional control of radiation from high-end infrared heat sources, efficiently concentrating emitted infrared energy into the target area. The result is significantly enhanced heating performance while substantially reducing the thermal load on the equipment itself.

Issue: A significant portion of the infrared source's radiation does not reach the workpiece.

In high-end heat source systems such as infrared heating, irradiation heating, and rapid thermal processing (RTP), the heat source emits radiation omnidirectionally. Only a portion of this radiation reaches the work area; the rest is absorbed by the reflector, chamber walls, and structural components, converting into internal equipment heat. This results in a dual cost:

• Effective power is dilutedReaching the target temperature requires increasing power and extending the heating duration.
• The device is overheating itself.Cavities, structural components, seals, and electrical parts endure sustained additional thermal loads, directly impacting lifespan, stability, and cooling system scale.

The reflectivity of the mirror is a critical variable in this link: for every percentage point lost, the energy isn't gone—it stays within the device.

Technical Breakthrough: Achieving Both High Reflectivity and Heat Resistance

Achieving both high reflectivity and heat resistance has long been a challenge in engineering: conventional high-reflectivity coatings tend to fail or lose reflectivity under high temperatures, thermal cycling, and prolonged service, while heat-resistant materials often offer limited reflectivity.

Tianyi Quan'an is based onHigh-Entropy Precursor Ceramics (HPEC)Material system: By tailoring composition and microstructure, we engineered a highly efficient multi-scattering interface that achieves 99.9% reflectance in the near- and mid-infrared bands while maintaining high-temperature stability and strong adhesion. The coating can be applied to surfaces surrounding heat sources—such as reflector housings and the inner walls of heating chambers—to function as a "directional optical interface" for thermal source systems.

Application Value: Radiative directional convergence for simultaneous performance and thermal load optimization

Increasing the reflectivity of the reflective surface to 99.9% delivers system-level benefits:

• Radiation Utilization:Radiation originally absorbed by the cavity is reflected back into the working area, significantly increasing effective radiant flux.
• Heating Performance:Heats up faster and reaches higher temperatures at the same power level; or requires less power to achieve the same process temperature.
• Device Thermal Load:Significantly reduced heat absorption in the cavity and structural components, lowering cooling load and thermal deformation risks.
• Service Life:The reflective surface maintains its reflectivity even at high temperatures, ensuring consistent long-term device performance.
• Energy Consumption:Reduced electricity consumption per unit of process output

Next Steps

The company states that the coating has completed key performance validation and is advancing along its engineeringization path. The extreme environment simulation test platform currently under construction is equipped with a high-power irradiation heating system, which will serve as one of the first real-world validation scenarios for this coating. Additionally, the company is collaborating with users in the infrared heating equipment and heat treatment sectors to conduct application adaptation and joint verification.
