There are two types of silicon nitride (SI3N4), both of which belong to the hexagonal crystal system. Both are three-dimensional spatial networks composed of tetrahedrons sharing vertices. There is only a difference in symmetry (α phase is relatively symmetrical), but there is no distinction between high and low temperature phases. The crystalline phase is the […]

Pyrolytic Boron Nitride, abbreviated as Pyrolytic BN or PBN, also known as Chemical vapour-deposited Boron Nitride, Chemical Vapour-deposition of Boron Nitride or CVD-BN, etc. As the name suggests, this is a kind of boron nitride prepared by high temperature pyrolysis reaction by chemical vapor deposition method. Pyrolytic Boron Nitride (PBN) material has high purity, chemical […]

Silicon nitride (Si3N4) ceramics have the advantages of high specific strength, high specific modulus, high-temperature resistance, oxidation resistance and wear resistance, and thermal shock resistance. The initial application of silicon nitride ceramics was mainly used in machinery, metallurgy, chemical industry, aviation, semiconductor, and other industries, as parts of certain equipment or products, and achieved good […]

Properties of Zirconia

February 21, 2024 Posts

Zirconia, also known as zirconia (ZrO2), is an inorganic non-metallic material with high temperature resistance, corrosion resistance, abrasion resistance and excellent electrical conductivity. In addition to the traditional use of refractory materials and ceramic pigments, ZrO2 is also used in high-tech fields such as electronic ceramics, functional ceramics and structural ceramics. Physical and chemical properties […]

Welcome to the exciting world of tungsten tubes and their limitless potential in industrial applications. Tungsten, known for its exceptionally high melting point and durability, has been a staple material in various industries for decades now. However, it is often overlooked in comparison to other metals like steel or aluminum. In this blog post, we […]

1. Zirconia refractory (1) Zirconia crucible The melting point of zirconia is as high as 2700℃. Even if it is heated to more than 1900℃, it will not react with molten aluminum, iron, nickel, platinum and other metals, silicates and acid slag, so the crucible made of zirconia material can be successful Locally smelt platinum, […]

1. Co-precipitation method The co-precipitation method is currently the most commonly used method for preparing nano-zirconia due to its simple operation, easy control of the reaction process, and low cost. The specific process of this method is: adding some stabilizers (such as Y(NO3)3) and dispersing agents (such as PEG2000, etc.) to make soluble zirconium salts […]

From biomedical imaging and aerospace engineering to consumer products and research initiatives, Nitinol Shape Memory Alloy (SMA) is revolutionizing the modern engineering landscape. This ultra-flexible, temperature-responsive metal has quickly become a highly sought-after material for its remarkable properties. With an ability to store vast amounts of energy and then recall it later on demand, Nitinol […]
