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
