Choosing High purity calcination α Alumina raw material and specially extracted Pure process treatment, our Spherical Alumina has good sphericity, high thermal conductivity. Meanwhile, we can provide customers with personalized solutions. It can be used in the industries below:
Thermal conducting filler: Applied in thermal conducting silica gel, silicone grease, thermal phase change pad and MC plate as thermal conducting filler so as to improve the thermal performance of the product.
Thermal conducting pouring sealant: Applied in the packege of some electronic elements which have higher requirement on the heating diffusion.
Honeycomb ceramics and ceramic filters: Good for the formation and uniformity of pore.
Grinding and polishing agent: applied in the fields such as equipment manufacturing, ornaments processing,mobile car repair and maintenence. The spherical appearance makes the polishing surface more smooth with fewer scratch due to higher Mohs hardness.
Basic Feature: High Sphericity: By adopting the technology owned by ourselves, the sphericity is more than 92% and spheroidization rate is more than 90%.
High purity: By choosing the high purity raw material and treating the surface impurities with special purification process, the aluminium oxide content is no less than 98% and the content of ion on the surface is low.
High thermal conductivity: The thermal conductivity of αtype alumina is higher than 90%, due to its surface is compact and seamless.
Particle size distribution：The precise control of product particle size distribution，can produce the narrow particle size distribution products with good particle size uniformity. We can also adjust the particle size according to different requirement.
High fluidity: Good recipe and high spheroidization rate make the fluidity and filling rate high.
- Q: What is the zinc oxide?
- Zinc oxide is an oxide of zinc. Hard to dissolve in water, soluble in acid and alkali. Zinc oxide is a commonly used chemical additive, widely used in plastic, silicate products, synthetic rubber, lubricants, paint coatings, ointment, adhesives, food, batteries, flame retardants and other products in the production. Zinc oxide band gap and exciton greater binding capacity, high transparency, excellent room temperature luminescence performance in the semiconductor field of liquid crystal display, thin film transistors, light-emitting diodes and other products are used. In addition, the micro-particles of zinc oxide as a nano-materials also began to play a role in related areas.
- Q: Is the oxide pure?
- Pure substances are divided into simple substances and compounds, oxides belong to the compound, naturally belong to the pure material
- Q: Oxide and organic peroxide signs
- An organic compound containing -O-O-peroxy functional group formed by replacing hydrogen atoms in hydrogen peroxide with an organic group such as an alkyl group, an acyl group, an aromatic group or the like. Characterized by heating more than a certain temperature will decompose to produce oxygen free radicals, unstable, easy to break down. Chemical production of organic peroxides is mainly used for synthetic resin polymerization initiator, catalyst. In the field of polymer materials, it can be used as a radical polymerization initiator, graft reaction initiator, rubber and plastic cross-linking agent, unsaturated polyester curing agent and spinning grade polypropylene in the preparation of molecular weight and Molecular weight distribution regulator. Environmental pollution in the air under the action of light through the free radical reaction can produce peroxy nitrates compounds, photochemical oxidants in one of the species. On the skin, eyes, mucous membrane has a strong irritant, is an important pollutant in the atmosphere. Such substances are flammable and explosive dangerous goods, the use should pay attention to safety. Generally, the active oxygen content, activation energy, half-life and decomposition temperature were used as the basis of selection.
- Q: Iron oxides and their properties
- There are iron oxide, Fe3O4, in fact, is FeO · Fe2O3, magnetic black crystal
- Q: Is SiO2 an amphoteric oxide?
- Not though SiO2 reacts with HF but the reason for this reaction is not because H + is because Si and F-coordination generated SiF4 is very stable.
- Q: What are the oxides of chlorine
- Dichloride, also known as chlorate (ClOClO3) hexahydrate (Cl2O6) dioxane (Cl2O7)
- Q: Acidic oxide is a kind of oxide which can form acid or react with water to form salt and water. Generally non-metallic elements of oxides and certain transition metal elements of high-priced oxide. Such as sulfur trioxide SO3, phosphorus pentoxide P2O5, manganese dioxide Mn2O7, chromium trioxide CrO3 and so on. Most of the non-metallic oxides are acidic oxides. In our familiar non-metallic oxides, carbon monoxide and nitric oxide are not acidic oxides, and are usually classified as non-acid oxides.
- React with the acid to produce salt and water, this oxide called alkaline oxide (and the product can only have salt and water, can not have any other substances generated). Alkaline oxides include low-valent oxides of active metal oxides and other metals such as Na2O, CaO, BaO and CrO, MnO.
- Q: Titanium oxide total of several?
- Ti2O3 titanium dioxide purple powder, hexagonal crystal structure, lattice constant α = 0.5155nm. Containing oxygen 59.5% ~ 60.8% (at). Density 4.486g / cm3. Melting point 1900 ℃. Soluble in 40% Hydrofluoric acid, can be concentrated nitric acid erosion, but not concentrated hydrochloric acid, concentrated sulfuric acid erosion, nor for alkali erosion, and 30% (mass) hydrogen peroxide solution to produce a slightly yellow solution. ~ 300 ℃ into titanium pentoxide. Vacuum in 1600 ℃ heated titanium powder and titanium dioxide mixture or 1500 ℃ hydrogen reduction of titanium dioxide. Titanium ion itself is an excellent reducing agent.
- Q: Clothes on the metal buttons and metal ornaments for a long time there will be a layer of oxide, looks bleak, what good way to make these metal accessories smooth shiny?
- Brush with vinegar or toothpaste
- Q: Do not say fluorine gas, it is the strongest element, do not say that electronic anti-matter and current, authority ah
- Oxygen is a colorless, almost odorless highly toxic gas, liquefied after the pale yellow. Because of the oxygen at room temperature with the dry air can react quickly to produce nitrogen dioxide and moldy colorless Gas nitrogen trifluoride (fluorine gas at room temperature with the dry air almost no reaction, which can be seen in the oxidation of tungsten fluoride), so usually see the fluoride is a brown odor of brown gas.
