Graphite Block

High-Purity & Fine-Grain Graphite Blocks

Engineered as the foundational material for demanding high-temperature applications, our graphite blocks feature high density, exceptional mechanical strength, and outstanding thermal shock resistance. Available in Isostatic, Vibrationally Molded, and Extruded grades, these blocks serve as raw material for precision-machined Graphite Crucibles and complex structural components across photovoltaics, semiconductors, and EDM tooling.

Ultra-Low Ash & Purity (< 5-20 ppm)

Purified to eliminate metallic contaminants, protecting sensitive wafer processing environments.

High Machinability

Uniform grain structure allows custom fabrication into fine details, such as Graphite Fasteners.

Excellent Homogeneity

Isostatic press molding ensures identical physical properties in all directions (isotropic).

Process Grade	Key Technical Advantage	Primary Process Application
Isostatic Graphite Block	Ultra-fine grain size (< 10 µm), uniform strength, high purity	CZ Silicon Crystal Growth, EDM Electrodes, MOCVD
Molded Graphite Block	Medium-fine grain, cost-effective, good thermal conductivity	Vacuum furnace hot zones, continuous casting dies
Vibrated Graphite Block	Large dimensions available, robust mechanical stability	Large heating elements, metallurgical sintering moulds
