Siliconized graphite crucible has the following advantages
1, long life: long-term use below 1200 degrees, no oxidation or very low oxidation rate

  2, does not absorb water, the surface produces a glass phase protective film.

  3, directly from the 1200 degree environment to room temperature, no cracks, no cracks.

  4. No harmful metal elements are introduced, and the carbonization effect is more ideal.
