Boron Nitride Ceramic Rod Forming Introduction

The boron nitride rods are made of boron nitride ceramics and are processed through the following series of steps: forming, grouting, grouting, drying, extrusion, cold, static pressure, hot pressing, hot isostatic pressing. They have excellent resistance to falling, abrasion, super strong, super hard, high temperature (refractory), super corrosion resistance, never rust, oxidation resistance and insulation performance. The reasonable combination of bending strength and elasticity gives the ceramic rods a high impact strength. Boron nitride ceramic rods are easy to maintain and require no paint or protective finish on the surface and cutting edges.

Different shapes, sizes and precision products require different forming methods during the molding of boron nitride ceramic rods.

Injection Molding

Process: purchase airflow powder → with chemical components → stir evenly → dry → break → injection molding

→ Discharge → Sintering → Post-processing

Injection molding is the first method used to make BN rods. By this method, a low-cost boron nitride ceramic can be mass-produced, and a special ceramic material having a special shape and a small size can be manufactured. However, this method cannot produce large-sized boron nitride products.

Isostatic Molding

Process: fill the powder into the rubber mold→ isostatic pressing → sintering → grinding and polishing

The advantage of isostatic pressing for the production of boron nitride rods is that the products have high density and high quality, and can be molded in large quantities; the disadvantage is that the equipment used is complicated and costly, and it cannot produce special shaped products.

Dry Pressing

Process: fill the powder to the rubber mold→ dry press forming → sintering → grinding and polishing

The dry pressing method can produce ceramic materials with special shapes and sizes, but it is only suitable for small-scale production rather than mass production.

Hot Press Forming

Process: first purchase airflow powder → with chemical components → stir evenly → put in material bucket → hot press forming → debinding → sintering → post processing

Hot press molding is easy to manufacture products with complex shapes, but it is not suitable for all materials.

Boron Nitride Ceramic Properties

Boron nitride is a white solid ceramic material, with a nickname of "white graphite" because of its similar appearance and structure. Boron nitride ceramic is an excellent material which has low porosity, good thermal conductivity, low dielectric constant and superior dielectric strength. It is easily machined into complex shapes, and then ready for use without additional heat-treating or firing operations. Boron nitride has a variety of different variants: hexagonal boron nitride (h-BN), rhombohedral boron nitride (r-BN), cubic boron nitride (c-BN) and wurtzite boron nitride (w-BN). The most commonly used in the industry are h-BN and c-BN. H-BN & C-BN Hexagonal boron nitride, abbreviated as hBN, is an electron body having a layered structure similar to graphite. It has good lubricity, electrical insulation, thermal conductivity, and chemical resistance, and also has the ability to absorb neutrons. It is made of nitrogen (such as urea, melamine, etc.) and boron (b

Temperature Tolerance of Various Advanced Ceramic Materials: Paving the Way for High-Performance Applications

In the realm of materials science, the quest for materials that can withstand extreme temperatures without compromising their structural integrity or performance has led to significant advancements in advanced ceramics. These materials, known for their exceptional thermal, mechanical, and chemical properties, are pivotal in industries ranging from aerospace to energy production, where high-temperature environments are commonplace. This article explores the temperature tolerance of various advanced ceramic materials, shedding light on their applications and the future of high-temperature technologies. Silicon Carbide (SiC) Silicon Carbide stands out for its exceptional thermal conductivity and stability, with a temperature tolerance that can exceed 2,500°C in non-oxidizing environments. Its remarkable resistance to thermal shock and wear makes SiC an ideal material for components in jet engines, gas turbines, and even as protective shields in space exploration vehicles.

Is Cubic Boron Nitride Harder than Diamond?

When it comes to the hardest materials on Earth, diamonds are often the first that come to mind, celebrated for their unmatched natural hardness and durability. However, in the world of materials science, another contender plays a crucial role in various industrial applications: cubic boron nitride (cBN) . This raises a compelling question: Is cubic boron nitride harder than diamond? Understanding Hardness and Material Science Hardness, in materials science, refers to a material's resistance to deformation, particularly permanent changes such as indentation or scratching. The hardness of a material is a crucial factor in its application, especially when it comes to cutting, grinding, and drilling technologies. Diamond: The Unsurpassed Natural Material Diamond, a crystalline form of carbon, has long been recognized as the hardest known natural material. Its extraordinary hardness makes it ideal for a wide range of applications, from jewelry to industrial cutting and drilling tools.
