蓝晶石
蓝晶石是一种新型耐火资料，属于高铝矿物，抗化学侵蚀功能强、热震机械强度大，受热收缩不可逆等，是消费不定形资料和电炉顶砖 、磷酸盐不烧砖、莫来石砖、低蠕变砖的次要原料，也是一种蜕变矿物，次要产于区域蜕变结晶片岩中，其蜕变相由绿片岩相到角闪岩相。也罕用作宝石戒面，手链，项链。
蓝晶石特点：
(1)热收缩性：蓝晶石矿物在加热进程直达化为莫来石和蓝晶石的混合物，在这个转化进程中，矿物随同着体积收缩，并且构成良好的英来石针状网络，体积收缩率16－18%。
(2)稳固性：蓝晶石矿物消费耐火资料稳固性比粘土质耐火资料高1.5倍。蓝晶石耐火砖比粘土砖的损耗低43%，比粘土砖寿命长150－200炉。
(3)耐火度高：普通粘土质耐火资料的耐火度为1670－1770℃，而蓝晶石的耐火资料通常大于1790℃，最矮小于1850℃。
(4)不可逆性：蓝晶石矿物煅烧成莫来石，是一个不可逆的转化。在温度1810℃以下它是稳固的。因而莫来石耐 火资料具备低温下体积稳固、收缩率低、抗化学侵蚀性强、机械强度高和抗热冲击才能强的特点。
蓝晶石用处
蓝晶石矿物次要用作消费耐火资料、氧化铝、硅铝合金和金属纤维等用处。
一、蓝晶石做耐火资料的优点
(1)在低温下体积稳固，不膨胀。
(2)比其余高铝耐火资料生老本低。
(3)功能好。比粘土砖损耗高压43%，耐火度高达1825°C以上。
(4)节约动力。热容比粘土砖高12%，用于马丁炉可缩短冶炼工夫，能耗少。
(5)退出不定形耐火资料中作低温收缩剂，使产品在低温下不膨胀和剥落。次要使用于冶金、建材、机械、化工、轻工、核工业告等行业。
二、蓝晶石做硅铝合金和金属纤维的优点
（1）比用分解法（用熔炼金属硅和电解铝）或用电热复原高岭土等办法老本低，经济效益高。
（2） 可满足制作汽车、宇宙飞船和雷达部件的非凡技术要求道的，冶金、机械、宇航等工业部门。
因而世界上对蓝晶石类矿物的开发利用越来越注重，特地是几个发达的国度，如在日本，蓝晶石是耐火混凝土、可塑料、高铝水泥的重要原料；美国和一些国度用蓝晶石预烧制成各种牌号的莫来石质熟料，宽泛地使用于陶瓷和精细铸造等部门；苏联用蓝晶石－硅线石精矿制作的轻质砖。采纳蓝晶石作收缩剂配制的不定型耐火资料在加热炉上的试用是胜利的，其外表裂纹少，应用中跑火景象也少，应用成果较好。总之蓝晶石是不定型耐火资料良好的收缩剂。

Kyanite
Kyanite is a new type of refractory material, which belongs to the high aluminum mineral, resistance to chemical corrosion resistance, thermal shock and mechanical strength, thermal expansion is not reversible, is does not produce amorphous materials and furnace top phosphate brick, brick, mullite brick and low creep brick is the main raw material, is also a kind of metamorphic minerals, mainly in the regional metamorphic crystalline schist and the metamorphic facies by greenschist facies to amphibolite facies. Also used as a gem ring, bracelet, necklace.
The characteristics of kyanite:
(1) thermal expansion: kyanite in the heating process into a mixture of Mo mullite and kyanite, in this transformation process, mineral, accompanied by volume expansion and formed good English to stone needle shaped network, volume expansion rate of 16 - 18%.
(2) stability: kyanite refractory production stability is 1.5 times higher than clay refractories. Kyanite refractory brick than clay brick 43% low loss, long service life than the clay brick 150 - 200 furnace.
(3) refractory high: General fireclay refractory refractory degree is 16701770 DEG C, and kyanite refractory material is usually greater than 1790 DEG C, highest more than 1850 C.
(4) irreversibility: kyanite calcined into mullite, is an irreversible transformation. It is stable at 1810 degrees Celsius. Therefore Mo mullite refractories with characteristics under high temperature and volume stability, low coefficient of expansion, anti chemical corrosion resistance and high mechanical strength and thermal shock resistance ability.
Use of Kyanite
Kyanite is mainly used for the production of refractories, alumina, silicon and metal fiber Aluminum Alloy etc..
Do the advantages of Kyanite refractories
(1) volume stability at high temperature, not shrink.
(2) lower than other high alumina refractory materials.
(3) good performance. The loss of low pressure 43% than the clay brick, the fire resistance of up to 1825 degrees C.
(4) energy conservation. 12% high heat capacity ratio of clay brick, for Martin can shorten the smelting time, less energy consumption.
(5) adding an amorphous refractory as a high temperature expansion agent, so that the product does not shrink and spalling at high temperature. Mainly used in metallurgy, building materials, machinery, chemical industry, light industry, nuclear industry and other industries.
Do the advantages of silicon Aluminum Alloy Kyanite and metal fiber
(1) compared with the synthesis method (using smelting metal silicon and electrolytic aluminum) or with the method of reducing kaolin and other methods of low cost, high economic efficiency.
(2) to meet the requirements of the manufacture of automotive, aerospace and radar components of the special technical requirements of the road, metallurgy, machinery, aerospace and other industrial sectors.
