What Is a Lab High Temperature Sintering Furnace, and Where Is It Used?

What Is a Lab High Temperature Sintering Furnace?
A lab hightemperature sintering furnace is a versatile, multifunctional industrial heating device that combines the advantages of openchamber batch processing from box furnaces with the atmospherecontrolled, sealedtube capabilities of tube furnaces. It integrates a sealed tube chamber inside the furnace or connects external tube components to the main boxtype chamber.

Shenyang Kejing's lab hightemperature sintering furnace can handle openair heating for multiple batches of samples like a traditional box furnace, while also enabling precise atmosphere control through sealed tubing—allowing the introduction of inert, reducing, oxidizing, or other specific gases, much like a traditional tube furnace. This design resolves the common dilemma where traditional furnaces either offer large batch capacity but poor atmosphere control, or excellent atmosphere control but limited processing volume. Additionally, our hightemperature electric furnace is compact and lightweight, making it easy to place inside glove boxes or fume hoods, ideal for labs and small pilot workshops with limited space—no need for extra dedicated floor area.

Where Can a Lab High Temperature Sintering Furnace Be Applied?
Lab high temperature sintering furnaces are widely used in material preparation and experimental scenarios requiring controlled heating atmospheres, batchprocessing capability, and uniform temperature distribution. These include annealing and carburizing of metal materials, sintering of ceramics, doping of semiconductor materials, and material synthesis experiments in universities and research institutes. Such applications demand precise atmosphere control and excellent temperature uniformity.

Our lab hightemperature sintering furnace is equipped with a φ50 × 230 mm singleend quartz tube and a stainlesssteel vacuum flange with a silicone Oring, two stainlesssteel shutoff valves, and a mechanical pressure gauge. The gas inlet features a φ6.35 mm ferrule fitting, and the outlet is a φ8 mm barbed connector. With the support of a mechanical pump, a vacuum level of up to 10⁻² Torr can be achieved. This vacuum environment prevents interference from impurity gases during metal annealing or carburizing, avoids oxidation during ceramic sintering, and allows the introduction of inert or specific reaction gases to meet the atmosphere requirements for semiconductor doping—ensuring stable heat treatment for processes sensitive to environmental purity.

Shenyang Kejing's lab high temperature sintering furnace reaches a maximum operating temperature of 1100°C (with a routine working temperature of 1000°C). It comes with an intelligent temperature controller and a PIDbased 30segment programmable temperature control system, paired with a Ktype thermocouple for precise temperature regulation. The 130 mm (L) × 100 mm (W) × 100 mm (H) heating zone accommodates batchprocessing needs for smallscale, multigroup material synthesis in academic research, as well as pilotscale treatment of small metal or ceramic samples in industrial settings. It is especially suitable for lab R&D and smallbatch production scenarios where heating atmosphere, temperature accuracy, and processing capacity are all critical requirements.

With a total production facility area of approximately 14,000 square meters, Shenyang Kejing maintains a professional R&D team and a complete workflow covering design, production, testing, packaging, and aftersales service. Choosing our lab high temperature sintering furnace will make your experiments and production more efficient!
