High purity calcium carbide crystals for B2B – China Source Factory

Pure & Uniform Calcium Carbide Crystals – Engineered for Industrial Precision

As a dedicated calcium carbide crystals manufacturer with over 15 years of experience, Tianjin Zhongying Chemical Co., Ltd. produces high-purity calcium carbide crystals that power critical industrial processes worldwide. Unlike powder or crushed irregular grades, our crystalline form ensures consistent particle size, predictable gas release, and minimal waste – making it the preferred choice for B2B buyers who value process stability.

Why Our Calcium Carbide Crystals Outperform Standard Grades

Our production base in Ordos, Inner Mongolia, leverages local energy and raw material advantages to manufacture calcium carbide crystals with:

• High gas yield (≥295 L/kg) – maximizes acetylene output per ton

• Uniform crystal structure – controlled size distribution from 2–4mm up to 80–120mm

• Low impurity profile – reduced phosphine and hydrogen sulfide for safer handling

• Excellent batch consistency – critical for large-volume industrial users

These calcium carbide crystals are not a byproduct; they are precision-engineered. Every batch undergoes rigorous in-house testing, and we can provide SGS, CIQ, or INTERTEK reports for full supply chain transparency.

Custom Sizes & Packaging – Built for Your Process

We understand that different applications require different crystal dimensions. That is why we offer calcium carbide crystals in eight standard ranges: 2–4mm, 4–7mm, 7–15mm, 15–25mm, 25–50mm, 50–80mm, and 80–120mm. Custom sizes are also available upon request.

For export, we package calcium carbide crystals in 50kg or 100kg new iron drums, with customized labeling and container loading plans to minimize moisture exposure during transit.

Trusted by Buyers Across Four Continents

With a stable monthly output of 6,000 tons of calcium carbide crystals, we serve hundreds of industrial customers in Southeast Asia, Africa, South America, and the Middle East. Our annual export volume consistently ranks among the top in China’s calcium carbide industry – not because we are the cheapest, but because we deliver what we promise: consistent calcium carbide crystals that work the same way batch after batch.

Applications for Our Calcium Carbide Crystals

• Acetylene gas production – welding, cutting, and chemical synthesis

• PVC manufacturing – as a key raw material for vinyl chloride monomer

• Steel desulfurization – removing sulfur from molten iron

• Mining engineering – for rock fragmentation and stone cutting
