Title:
POROUS SHEETLIKE REFRACTORY AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPH05310481
Kind Code:
A
Abstract:

PURPOSE: To obtain a sheet having low reactivity with a product without causing uneven burning by forming moderate pores and reducing the thickness in a porous sheetlike refractory used for burning electronic parts.

CONSTITUTION: The objective porous sheetlike refractory is obtained by bonding 50-90 pts.wt. aggregate having ≥30μm diameter composed of a refractory material with 10-50 pts.wt. inorganic binder having ≤10μm diameter in a ceramic tool used for mainly burning electronic parts. Alumina, mullite, zirconia, magnesia, spinel or andalusite can be used alone or in combination with these aggregate and inorganic binder. The apparent porosity thereof is ≥10% and its thickness is 0.3-5mm. The method for producing the sheetlike refractory is to form a green sheet by wet molding according to the extrusion or roll molding.
