How It's Made

The production of ceramic fiber bulk involves several key steps:
1️⃣ Melting Raw Materials – High-purity clay clinker, alumina, and silica powder are melted in an industrial furnace at extreme temperatures.
2️⃣ Forming Fibers – The molten material is turned into fine fibers using compressed air spraying or spinning techniques.
3️⃣ Collection & Shaping – The fibers are collected into ceramic fiber bulk and can be further processed into blankets, boards, paper, and fabrics.
