Extrusion porcelain tube with low expansion coefficient
The invention discloses an extruded porcelain tube with a low expansion coefficient. The extruded porcelain tube is prepared from the following materials: 35 +/-5% of aluminum oxide, 50 +/-5% of silicon dioxide, 1 +/-0.1% of ferric oxide, 0.5 +/-0.05% of calcium oxide, 12.5 +/-1% of magnesium oxide, 0.5 +/-0.05% of potassium oxide, 0.5 +/-0.05% of sodium oxide, 0.4 +/-0.05% of titanium oxide, < = 0.01 +/-0.01% of zirconium dioxide ZrO2, < = 0.05 +/-0.05% of barium oxide, 0.1 +/-0.01% of phosphorus pentoxide and 0.05 +/-0.01% of others. The extrusion porcelain tube with the low expansion coefficient solves the problem of large temperature difference, improves the radiation electric ceramic furnace, and is stable in temperature control performance and more accurate in temperature control.
本发明公开了一种低膨胀系数的挤压瓷管，该挤压瓷管的材料如下：35±5％的三氧化二铝、50±5％的二氧化硅、1±0.1％的三氧化二铁、0.5±0.05％的氧化钙、12.5±1％的氧化镁、0.5±0.05％的氧化钾、0.5±0.05％的氧化钠、0.4±0.05％的氧化钛、≤0.01±0.01％的二氧化锆ZrO2、≤0.05±0.05％的氧化钡、0.1±0.01％的五氧化二磷、0.05±0.01％的其他。该种低膨胀系数的挤压瓷管，解决温差大的问题，提高辐射电陶炉，温控性能稳定，温控更加精准。
