Refractory Zirconia Crucibles-manufacture,factory,supplier from China

Zirconia melting point up to 2700 °C, heat resistance, corrosion resistance is excellent, is one of the refractory materials with excellent refractory function in nature, its slag resistance is strong, the thermal conductivity decreases with the increase of temperature, even if heated to more than 1900 degrees Celsius will not have an effect with molten aluminum, iron, nickel, platinum and other metals, silicates and acid slag, so it can be used to make crucibles that melt precious metals, refractory ceramic tubes, etc.

Jinan Jingpu Ceramic Material Co., Ltd. since its inception, has gone through more than ten years of ups and downs, we always adhere to the corundum crucible, alumina crucible, zirconia crucible, zirconia crucible product quality for our work of the top priority, high-quality quality does bring us rich returns, but with the development of the industry is becoming more and more mature, we deeply realize that relying on excellent quality alone is also difficult to cope with fierce market competition, where will enterprises go?

 Crucibles serve as containers for samples during thermoanalytical measurements. The performance of crucible used for a measurement can have a large effect on the quality of the results obtained. Our alumina crucibles have four remarkable characteristic as follow:. Good thermal conductivity: Ensure optimum heat transfer with the lowest possible temperature gradients between the sample and the sample holder.. An inert material : No physical or chemical transitions, not react with the sample in the temperature range used..

Thermal analysis is an analytical method of measuring the properties and behavior of matter that involves exposing a sample to a controlled temperature to observe its physical and chemical changes. Alumina crucibles are a common tool used for firing or heat-treating samples at high temperatures. High-purity alumina crucibles are mainly made of alumina materials, which are processed by high temperature and chemical cleaning.

Alumina ceramic is a kind of industrial ceramic with high hardness, which can only be processed by diamond grinding.Characteristics of Alumina Ceramics1, alumina ceramic hardness2, alumina ceramic wear resistance is very goodIts wear resistance is equivalent to 266 times of manganese steel, according to our customer tracking survey for more than ten years, in the same working conditions, can extend the service life of the equipment at least ten times more.3, Alumina ceramics light weightIt can greatly reduce the equipment load.The difference between alumina ceramics and ordinary ceramicsThe ma

Relying on the exact specs that your element or aspect require, the choice might also additionally fall on one of the one of a kind industrial grades of alumina currently available:Smelter gradeMetallurgical or smelter grade alumina is the shape of alumina used for manufacturing aluminum porcelain. it’s crafted from aluminum hydroxide in each fluid flash calciners or in fluid beds.

Along with the development and progress of science and technology, Thermal Analysis will have more and more applications. Jinan jingpu Ceramic material Co,Ltd is the first manufacturer of alumina sample pan for themal analyzers in China and have more than ten years of experiences in this field. Al2O3 content of alumina sample pans is more than 99%.The minimum wall thickness may achieve 0.2-0.3mm, used in different types of thermal analyzers .they have extreme high temperature stability due to double- firing process.We have many customers both in Chi

Alumina ceramics are Al2O3 as the main raw material, corundum (a-Al2O3) as the main mineral composition of a fairly important ceramic material, to the ingredients or matrix of the Content of Al2O3 to classify: Customary Al2O3 content of about 99% of ceramics called 99 porcelain, the content of 95% and 90% of the order called 95 porcelain and 90 porcelain. Ceramics with a content of more than 85% are usually called high alumina porcelain, and those with a content of more than 99% are called corundum porcelain or pure corundum porcelain.

The brand new era of commercial components is alumina ceramics, that allows you to replace conventional steel components, due to the fact ceramics have properly performance and high availability, which can similarly enhance the performance of the system.Excessive-purity alumina ceramics may be made into molten laminated glass to update platinum tongs pots, and also can be used as excessive-strain sodium lamp tubes with its light transmittance and resistance to alkaline earth metallic corrosion; 99 alumina porcelain raw materials are key to making high-temperature tongs pots , hearth-proof furn

Recently, there has been a new development in the field of alumina porcelain boats. A Chinese company has successfully developed a new type of alumina porcelain boat, whose main features are high strength, high toughness, high temperature stability and anti-corrosion performance. The alumina ceramic boat can not only withstand chemical tests in a high temperature environment, but also perform well in terms of corrosion resistance and wear resistance.
