Isostatic graphite is a type of graphite with an ultra-fine grain. It is used for applications where the mechanical properties of other fine-grained graphites are inadequate.

Silicon carbide (SiC) ceramic is a type of advanced ceramic material known for its exceptional properties and wide range of applications. It is composed of silicon (Si) and carbon (C) atoms arranged in a crystal lattice structure, resulting in a hard and strong material with excellent thermal and electrical conductivity.

Semiconductor manufacturing, the cornerstone of modern technological advancement, is in constant pursuit of smaller, faster, and more efficient integrated circuits. This relentless pursuit drives the need for increasingly precise and sophisticated manufacturing processes, where each step relies heavily on high-performance, high-quality, and high-precision equipment. Silicon carbide (SiC), a high-performance structural ceramic material, plays a crucial role in this demanding environment.

Silicon carbide ceramics offer numerous advantages in the optical fiber industry, including high-temperature stability, low thermal expansion coefficient, low loss and damage threshold, mechanical strength, corrosion resistance, good thermal conductivity, and low dielectric constant. These properties make SiC ceramics an ideal material for fiber optic sensors, lasers, and high-power optical fiber applications. As demand in the optical fiber field increases, the application prospects for silicon carbide ceramics will become increasingly prominent.

The four main molding methods for graphite molding are: extrusion molding, molding, vibratory molding and isostatic molding. Most of the common carbon/graphite materials on the market are molded by hot extrusion and molding (cold or hot), and isostatic molding is a method with leading molding performance. Vibration molding is generally used to manufacture medium and coarse structural graphite, particle size between 0.5-2mm particle size, generally dominated by di-roasted graphitized products, density between 1.55-1.75kg/m³, coarser particles, rougher surface, can not be used for precision machining. It is mainly used in chemical industry and metal smelting.
