α-β-Alumina Block(RTK-A)

Fused Cast α-β Alumina Block (RTK-M)

RTK-M is composed of about 50% each of α-alumina and β-alumina , and the interlocking of the two crystals forms a very dense structure with excellent resistance to strong alkalis.

Its resistance to erosion of molten glass is comparable to that of AZS in the temperature range below 1350℃. Since it contains almost no impurities such as Fe203 and Ti02, the matrix glass phase is very small, and it has the excellent property of not contaminating the molten glass by minimizing the occurrence of foreign matter such as bubbles when in contact with the molten glass.

Therefore, it is the most suitable for working pool wall, pavement, material channel and channel of high-grade glass furnace.

The above values are the typical physical and chemical indicator of the block material, but not as a basis for guarantee.
