- Q:What kinds of minerals are there in the five major categories of ore crystal chemistry?
- Sulphide. A total of more than 200~300 kinds, followed by the type of silicate minerals, the weight of 0.25% of the crust. Chang Fu is an important nonferrous metal deposit, which is an important source of copper, lead, zinc, antimony and so on. It is of great economic value. The main features are: metal luster, color, streak is deep, low hardness, good thermal conductivity, than the major. Another feature is that because sulfides are often associated with magma, it is very easy to oxidize under the surface supergene action. Except for pyrite (6 ~ 6.5 hardness), the hardness is very low. Such minerals pyrite, chalcopyrite, galena, FeS2 CuFeS2, PbS, Sb2S3, stibnite sphalerite molybdenite, cinnabar HgS MoS2.
- Q:What are the characteristics of high alumina bricks?
- High thermal stability, fire resistance above 1770. Slag resistance is good, used for masonry steel smelting furnace, glass furnace, cement rotary furnace lining. High R.U.L, low creep high alumina brick with high grade bauxite, fused corundum, fused mullite as main raw material of high-grade refractory materials.
- Q:What are ordinary bricks, refractory bricks, hollow bricks?
- Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material
- Q:What is the standard classification of high alumina bricks and high alumina bricks?
- High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. High alumina brick refractory clay brick and brick than refractoriness to high. It belongs to high refractory. High alumina brick Al2O3 more, close to the neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkaline slag resistance than acid resistant slag ability is weaker.According to the number of AL2O3 content is divided into, 55,65, 75,80 and so on several grades.
- Q:What is the difference between metal compounds and metal solid solutions?
- Solid solution refers to the alloy phase in which the solute atoms are dissolved into the solvent lattice and remain solvent type. A crystalline substance consisting usually of atoms or molecules in which a chemical substance is dissolved as a base; other substances are found in alloys and silicate systems; also present in polyatomic substances. The mixture can be treated as a solution when the crystal structure of the solvent can be stabilized and homogeneous after addition of solute. Some mixtures can form solid solutions in many concentrations, while some mixtures do not form solid solutions at all.
- Q:Use of high alumina refractory bricks?
- Because of the high Al2O3 high aluminum products, low impurity content, the formation of fusible vitreous body less so than the clay brick high load softening temperature, but because mullite crystallization has not formed the network organization, so the load softening temperature is not high silica brick.
- Q:What is the apparent porosity of high alumina brick?
- In the production of high alumina bricks in addition to the entity, there are many different sizes and shapes of different pores, pores can be divided into three categories: one side closed the other side and the outside world is called open pores, closed in the product not communicated with the outside is called closed pores, penetrating through pores called the few products.
- Q:Can high alumina brick resist carburizing?
- It is heavy brick mullite brick, brick to do the heavy weight to more than 2.4 manufacturers can achieve a few feeling
- Q:What should be used as binder for making high alumina bricks?
- In addition, high alumina micro powder can be used as binding agent, or high alumina micro powder and clay powder are prepared according to a certain proportion, and synthetic mullite is used as bonding agent. With these binders, high alumina bricks without two expansion can be prepared.
- Q:How high can aluminum bricks expand at 80O degrees of heat?
- When an object is heated, the particle moves faster and thus occupies additional space. This phenomenon is called dilation.
