Key Features<\/b><\/b><\/span><\/h3>\n

1. <\/b>Extreme Oxidation Resistance<\/b><\/b><\/span><\/h4>\n

The TaC coating forms a protective Ta\u2082O\u2085 glass layer<\/b>\u00a0under oxidizing conditions, significantly reducing oxidation rate.<\/span><\/p>\n

At 800\u202f\u00b0C in air:<\/span>
\u2022 Uncoated graphite: 12 mg\/cm\u00b2\u00b7h<\/span>
\u2022 TaC-coated plate: 0.3 mg\/cm\u00b2\u00b7h<\/b><\/span><\/p>\n

2. <\/b>Enhanced Mechanical Integrity<\/b><\/b><\/span><\/h4>\n

The gradient microstructure between TaC and graphite reduces interfacial thermal stress by up to 67%<\/b>, preventing delamination or cracking under thermal cycling.<\/span><\/p>\n

Strength improved by 3\u00d7 in Semicera Lab testing when base strength \u2265 80 MPa.<\/span><\/p>\n

3. <\/b>Thermal Load Durability<\/b><\/b><\/span><\/h4>\n

Maintains structural stability under 1800\u202f\u00b0C \/ 10 MPa<\/b>, with 8\u00d7 longer endurance<\/b>\u00a0than uncoated graphite plates.<\/span><\/p>\n

4. <\/b>Chemical Inertness in Harsh Gases<\/b><\/b><\/span><\/h4>\n

Resistant to H\u2082, HCl, NH\u2083, and other aggressive atmospheres, making it a reliable option for MOCVD, PECVD<\/b>, and high-purity furnace systems.<\/span><\/p>\n

Typical Applications<\/b><\/b><\/span><\/h3>\n

Semiconductor Industry<\/b><\/span><\/p>\n

MOCVD carrier plates and susceptor bases<\/span><\/p>\n

Crucibles, guide rings, and thermal shields in SiC crystal growth<\/b><\/span><\/p>\n

Aerospace & Defense<\/b><\/span><\/p>\n

High-temperature insulation and thermal barrier components<\/span><\/p>\n

Energy Systems<\/b><\/span><\/p>\n

Neutron moderator substrates and high-load support components under vacuum\/inert conditions<\/span><\/p>\n

\u00a0<\/span><\/p>\n

\u00a0Customization & Ordering<\/b><\/span><\/p>\n

\u00a0<\/span><\/h3>\n

Custom shapes and dimensions available<\/span><\/p>\n

Coating thickness and porosity tailored to your process needs<\/span><\/p>\n

Rapid prototyping and volume production supported<\/span><\/p>\n

\u00a0<\/span><\/p>\n

<\/b>Quality Assurance<\/b><\/b><\/span><\/h3>\n

All plates are produced under ISO-compliant systems, using ultra-pure precursors and CVD-grade reactors<\/b>\u00a0to ensure consistent quality, repeatable coating adhesion, and superior surface integrity.<\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n
