1. Material research and development
Metallic materials
Heat treatment: Improving metal hardness, toughness, or plasticity through processes such as annealing, normalizing, quenching, etc. (such as quenching tool steel to enhance wear resistance).
Phase transformation research: Observing the crystal structure changes of materials at high temperatures (such as martensitic transformation and austenitization processes).
Alloy preparation: controlling temperature gradient to achieve uniform diffusion of alloy elements (such as solid solution treatment of nickel based high-temperature alloys).

Ceramics & Glass
Sintering molding: Densifying powder materials at high temperatures (such as sintering alumina ceramics to 98% theoretical density).
Glass hot bending: Complex curved glass forming is achieved through programmed temperature control (such as 3D cover glass processing for mobile phones).

composite material
Carbon fiber pre oxidation: Stabilize the fiber structure at 200-300 ℃ and improve subsequent carbonization efficiency.
Ceramic based composite materials: SiC/SiC composite materials prepared by high-temperature hot pressing sintering (used for aircraft engine blades).

2. Manufacturing of electronic components
Semiconductor Process
Oxidation diffusion: Thermal oxidation of silicon wafers at 800-1200 ℃ to generate SiO ₂ insulation layer (thickness control accuracy ± 1nm).
Metalization annealing: eliminates stress on sputtered aluminum film and reduces contact resistance (such as MOSFET gate ohmic contact optimization).

Electronic ceramics
MLCC (Multilayer Ceramic Capacitor): Organic binders are removed and densified through adhesive sintering (sintering temperature 1250-1350 ℃).
Piezoelectric ceramics: achieving piezoelectric effect after polarization treatment (such as lead zirconate titanate PZT material).

Package Testing
Chip packaging: Achieving reliable connection between solder balls and substrates in reflow soldering process (peak temperature 260 ℃).

3. New energy and environmental protection
Lithium battery materials
Positive electrode material synthesis: High temperature solid-phase synthesis of LiCoO ₂ and NCM ternary materials (calcination temperature 800-1000 ℃).
Negative electrode material modification: The graphite surface is coated with an amorphous carbon layer (improving the initial Coulombic efficiency to over 90%).

Catalytic materials
Catalyst support: Preparation of high specific surface area Al ₂ O3 support (pore volume 0.8-1.2cm ³/g).
Waste gas treatment: Precious metal catalysts (such as Pt/Al ₂ O3) decompose VOCs at 500 ℃ (removal efficiency ≥ 95%).

solid waste treatment
Pyrolysis incineration: Medical waste is treated harmlessly at temperatures above 850 ℃ (with a 99.99% decomposition rate of dioxins).
Fly ash stabilization: fixing heavy metals in a glassy matrix through high-temperature melting (leaching concentration below the national standard limit).
