Break rings, a transitional element between the hot and cool zones of a continuous casting line, are made from hot-pressed boron nitride ceramics that have been machined. This is an important but frequently disregarded step in the casting process. The melt must be able to pass through the break ring and into the solidification zone without adhering. It must also be able to tolerate extreme temperature changes. Break ring failure can be quite expensive. For this reason, materials with low friction coefficients and strong thermal shock resistance are perfect. BN are excellent in this field.

Lanthanum hexaboride (lanthanum boride, or LaB6) is an inorganic nonmetallic compound made up of low-valence boron and the uncommon metal element lanthanum. It is a refractory ceramic that can survive extreme temperatures and hard conditions. Lanthanum hexaboride ceramic has many applications due to its superior thermal, chemical, and electrical characteristics.

In the ceramic industries, Pyrolytic Boron Nitride (PBN), Aluminum Nitride (AlN) and 99.8% Aluminium Oxide (Alumina) are used commonly for the OLED industry.

​ Although 99.7% boron nitride is white and offers strong electrical insulation, its lubricating capabilities, effective thermal conduction, and ease of machining make it comparable to graphite. It can also hold most molten metals since they don't wet it. Applications involving abrupt temperature fluctuations can benefit from its exceptional resilience to thermal shock. It won't react or get wet w

The molybdenum-manganese process is the most widely used metallization technique for BeO ceramics. The process involves applying a paste-like mixture of metal oxides and pure metal powder (Mo, Mn) to the ceramic surface, followed by high-temperature heating in a furnace to create a metal layer.

When it comes to the horizontal continuous casting of nonferrous metals, SNBN (boron nitride+silicon nitride) composite ceramics perform exceptionally well. The rings are perfect for guaranteeing a steady and clear separation during metal flow since they are non-wetting to molten metal, oxidation-resistant, and chemically inert.

Melted silicon is infused into a porous carbon or graphite preform to create reaction-bonded silicon carbide. Its production method with a coarse grain is the least expensive. It offers greater thermal conductivity but somewhat lower hardness and usage temperature.

The process known as "hot isostatic pressing," or "HIP," is used to enhance the mechanical qualities and integrity of materials. It entails simultaneously applying high pressure and temperature to a material. In the HIP process, an inert gas is used to pressurize a material that is heated to a predetermined temperature inside a pressure vessel. High pressure and temperature work together to remove internal flaws in castings, like pores or voids, and solidify powder metallurgy materials into completely dense components.

In essence, hot press sintering is a high-temperature dry pressing procedure. Even while its precise shapes vary, the basic procedure is essentially the same: the powder is filled into a mold, pressure is applied to the powder using upper and lower punches while it is heated, and simultaneous forming and sintering is achieved.

Materials are sintered under high-pressure gas conditions in a process called gas pressure sintering, which enhances densification and material qualities. Materials with high melting points or those that are challenging to sinter using conventional techniques benefit most from it.
