Effects of additives on the sintering properties and electric conductivity of nife2 o4 spinel anode materials 掺杂对镍铁尖晶石阳极材料烧结性能及电导率的影响
2.
The quality is a burnt magnesia spinel brick made from fused magnesia ， low iron sintered magnesia and fused hercynite . this synthetic hercynite is a patent by rhi refractories 它由电熔镁砂、低铁烧结镁砂和电熔铁铝尖晶石制成的烧结镁铁尖晶石砖，这种人工合成的铁铝尖晶石是rhi奥镁公司的专利。
3.
Despite the reduced alumina content ， the tensile strength of magnesia - hercynite and magnesia - galaxite bricks is kept at a much higher level compared to conventional top grade ma - spinel bricks even at high temperatures ( 1100 ) 尽管减少了氧化铝的含量，但即使是在1100度的高温下，镁铁尖晶石砖和镁锰尖晶石砖的抗拉强度仍然比常规的顶级镁铝尖晶石砖高很多。
