Embodiment 1
[0017] The ultra-low expansion ceramic pot in this embodiment includes a ceramic body and a glaze applied to the surface.
[0018] The main material of the ceramic green body is as follows by weight percentage: petalite feldspar 48%, spodumene 10%, kaolin 35%, quartz 5%, calcined talc 2%. Add crystallization agent Ta to the green body 2 o 5 , and its consumption is 0.2% of the above-mentioned body main material total amount by weight percentage.
[0019] The glaze contains 55% petalite, 20% spodumene, 6% kaolin, 8% quartz, 2% calcined talc, 6% barium carbonate and 3% zinc oxide by weight percentage. In addition, zirconium silicate or ceramic pigment is added, and its consumption is 4% of the total amount of the above-mentioned glaze material by weight percentage.
