Tender description

Spark Plasma Sintering System. Note that the SPS will be used mainly for relatively small samples with diameter of 10-13 mm. The typical sintering temperature range is 500-1800 ºC for the 10-13 mm samples. One Spark plasma sintering system. 1) Maximum working temperature: ≥2,200 C (Essential); 2) Maximum sample diameter: ≥60 mm (Essential); 3) Minimum sample diameter: ≤10 mm (Essential). Note that the SPS will be used mainly for relatively small samples with diameter of 10-13 mm. The typical sintering temperature range is 500-1 800 ºC for the 10-13 mm samples. 4) Maximum pressing force: ≥60 kN (Essential); 5) Minimum pressing force: ≤1 kN (Essential); 6) Piston stroke: ≥100 mm (Essential); 7) Displacement transducer accuracy: at most 3 μm (Highly desirable); 8) Maximum continuous DC current: ≥3 000 A (Essential); 9) DC Pulse Generator: On /Off control system (Essential); 10) Maximum heating rate: ≥500 C/min (Highly desirable); Minimum heating rate: ≤ 5 C/min (Highly desirable) 12) Sintering atmosphere: Inert gas Ar and He, vacuum (25 – 2 200 ºC) (Essential) 5 %H2/95 %Ar (25 – 1 500 ºC) (Highly desirable) 1 %O2/99 %Ar (25 – 1 200 ºC) (Desirable) 13) Vacuum: 5 Pa (Essential) 5 ×10-2 Pa (Highly desirable) 14) Temperature measurement: pyrometer and thermocouples are included (Essential), 15) Cooling: a suitable chiller unit is included (Highly desirable).
