Refractory Mullite kiln tray for sintering electronics parts and
powder
1. Description
The product is made from high quality synthetic mullite,through
high pressure molding and sintering.It makes Mullite as main
phase,with features of good thermal shock resistance,high
strength,no deformation, no shrinkage, no slag off,and other
advantages.
It is widely used in high temperature furnace , like magnetic
material and electronic ceramic and so on.
Mullite kiln tray is also known as mullite tray, mullite sagger and
mullite sagger box.
The firing sagger support protection products is a special
refractory kiln to continue to withstand the cold, thermal cycling,
thermal shock kiln materials characterization is important for
today's users saggar use higher and higher temperatures,
requirements and longer service life, more and more high quality
requirements, understand the whole situation, has not reached the
ideal level.
The sagger is produced by the sequential steps of: blending,
molding and sintering, wherein fused mullite, plate-shaped
corundum, aluminum oxide micro powder, silicon micro powder,
calcium aluminate cement and sodium hexametaphosphate are blended,
the materials are molded by adopting a self-flowing pouring molding
method, and after demoulding and drying, the materials are sintered
at high temperature to produce the corundum-mullite sagger. The
produced corundum-mullite sagger has the advantages of high
temperature resistance, good thermal shock stability and long
service life.
