摘要:
In a furnace for sintering non-oxidic ceramics, particularly Si₃N₄, which comprises a space for accommodating a ceramic shaped body (12), carbon heaters (8) arranged around the ceramic shaped body in said space and heat insulating layers (13) of carbon fiber mat that cover the inner walls of the furnace, sheetings (18) of laminated graphite leaves having an ash content of not more than 0.3% by weight are provided between said heat insulating layers (13) and said ceramic shaped body (12). The carbon heaters are of high purity graphite having a carbon content of at least 99.9980%, a silicon content of not more than 5 ppm and an iron content of not more than 9 ppm by weight. These measures protect the shaped body from harmful influence of carbon fiber dusts liberated from the insulating layers during sintering.
摘要(中):
在用于烧结非氧化陶瓷,特别是氮化硅,它包括一个空间,用于容纳碳的在所述空间和绝热层围绕陶瓷成形体布置在陶瓷成形体(12),碳加热器(8)(13)的炉 纤维毡确实覆盖炉的内壁,所述热绝缘层(13)和所述陶瓷成形体(12)之间设置具有按重量计不大于0.3%的灰分含量层压石墨叶片(18)片材。 碳加热器是具有至少99.9980%,不超过5ppm的和在按重量计的铁含量不超过9 ppm的硅含量的碳含量的高纯度石墨制成。 这些措施保护状体从烧结过程中从绝缘层中释放碳纤维粉尘的有害影响。
