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 500-1800 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); 11) 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).
