Core Insights - The Chinese space station has successfully implemented 58 scientific and application projects in orbit since 2025, achieving significant advancements in space materials science experiments, including setting a new world record for heating tungsten alloy to over 3100 degrees Celsius [1][4]. Group 1: Technological Breakthroughs - The "space furnace" located in the Chinese space station has successfully heated tungsten alloy to over 3000 degrees Celsius, nearing half the temperature of the sun's surface, which expands the range of materials available for future experiments [4][9]. - Two key technological breakthroughs are highlighted: the "suspension technique" and the "three-flame true fire" [9][17]. - The "suspension technique" allows liquid metals to be suspended in a microgravity environment, preventing contamination and interference, thus achieving a "containerless" state [11][13]. - The "three-flame true fire" utilizes a dual-wavelength laser system to heat metals, enabling even high-melting-point materials like tungsten alloy to be melted into liquid spheres [15][17]. Group 2: Future Applications - The advancements in material science could lead to the development of new heat-resistant materials that may serve as protective armor for spacecraft during atmospheric re-entry or as critical components in rocket engines operating under extreme temperatures [21].
