Product descriptions from the supplier
Calcium silicate board is a high-temperature insulation material widely used in industrial furnaces, kilns, and boilers. Made primarily from xonotlite crystals and reinforced fibers, it combines excellent thermal insulation, mechanical strength, and dimensional stability under severe heat exposure. Unlike flexible materials such as ceramic fiber, calcium silicate board serves as both an insulator and a structural support layer, providing lasting performance and energy efficiency in demanding thermal environments.
1. Composition and Microstructure Firebird’s calcium silicate boards are composed of high-purity quartz (SiO₂), lime (CaO), and glass or carbon fibers as reinforcement. During production, these materials undergo a hydrothermal synthesis process inside a pressure vessel, forming xonotlite crystals (Ca₆Si₆O₁₇(OH)₂) — a needle-like, porous structure.
This xonotlite structure creates a network of microscopic hollow spheres and channels that:
• Trap air for excellent thermal insulation
• Maintain rigidity under load
• Resist thermal shock and cracking
• Remain dimensionally stable up to 1100°C
The boards are 100% asbestos-free, chemically inert, and electrically insulating when dry, making them safe and sustainable for industrial use.
2. Available Grades and Types
Mingfa produces multiple grades of calcium silicate boards to serve different industries and installation needs.
(1) Standard Grade – 1000°C Series
Density: 170–270 kg/m³
Thermal conductivity: 0.06–0.12 W/m·K
Typical use: boiler walls, kiln linings, duct insulation, heat treatment furnaces
(2) High-Temperature Grade – 1100°C Series
Density: 250–500 kg/m³
Compressive strength: up to 5 MPa
Used in: steel reheating furnaces, glass regenerators, cement preheaters, and power plant ducts
(3) High Density Calcium Silicate Board
Density: 850–1200 kg/m³
Thermal conductivity: 0.09–0.18 W/m·K
Features: non-wettability to molten aluminum, high thermal shock resistance, CNC machinability
Applications: launders, spouts, hot-top rings, end dams, furnace lids
Comparable to international grades such as Marinite A, N-14, and M1A, Mingfa HD boards deliver strength and stability in environments where other insulations cannot survive.
