It is found that there is a mineral association, micro-crystal muscovite and phengite, in this deposit. The mineral assemblage contains about 80% micro-crystal muscovite and about 20% phengite. Their crystallinity is very high and their polytype is 2M1. Both of them are dioctahedral because the d and b of micro-crystal muscovite and phengite are 0.1502 nm, 0.9012 nm and 0.1505 nm, 0.9030 nm, respectively. For their d and b are larger than those of common muscovite, the reason why Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+) are high in the ore is that Al(superscript 3+) in the octahedron is replaced by Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+), and this is a phengite series mineral association formed through isomorphic replacement.

该矿物组合中的微晶白云母和多硅白云母结晶度高，多型为2M1，其含量分别为80%和20%左右；二者都属二八面体型白云母类矿物，但d060和b值偏大，微晶白云母的d060=0.1502nm，b=0.9012nm，多硅白云母的d060=0.1505nm，b=0.9030nm；微晶白云母矿铝含量较低、铁镁含量较高，其原因是白云母晶体铝氧八面体中的Al离子被Fe、Mg等离子所取代，这一矿物组合是通过矿物类质同象作用所形成一种多硅白云母系列矿物。

MgO-C brick has a good erosion resistance but Al〓O〓-C brick is better. Corrosion mechanism for refractory without carbon is that FeO and oxides of molten slag take place chemical reaction with constituents of refractory and forming low fusing point compounds to be dissolved in molten slag. For those refractory containing graphite carbon is to be decarburized in advance and to form decarburizing layer and metamorphosis layer. The subsequent corrosion is decarburizing and taking chemical reaction to form low fusing point compounds and dissolved in molten slag at the same time.

铁浴中硅和钛的扩散是影响铁浴及熔渣与耐火材料作用的重要因素，耐火材料中添加的TiO〓和SiC受熔渣氧化和侵蚀，将被部分还原形成Si，Ti向铁浴中扩散，Si、Ti在铁浴中的扩散研究结果是： D〓=1.84×10〓exp（－5988.7/T） cm〓/S E〓=49766 J/mol D〓=7.76×10〓exp（－53225.5/T） cm〓/S E〓=442304 J/mol 铁浴式熔融还原熔体对粘土砖，高铝砖，镁砖的侵蚀速度很高，镁碳砖抗侵蚀能力比前几种耐火材料强，但不如铝碳砖；对不含碳耐火材料在熔体中的侵蚀是熔渣中FeO及其它氧化物与耐火材料组分的化学反应形成低熔点物熔蚀进入渣相，产生损毁。
