Abstract
A gasifier internal refractory coating has at least one region of a sintered material containing at least 45% by weight of chromium oxide (Cr2O3) and at least 1% by weight of zirconium oxide, at least 20% by weight of the zirconium oxide (ZrO2) being stabilized in the cubic and/or quadratic form.
Claims16
A gasifier internal refractory coating composition having at least one region of a sintered material containing
- at least 45% by weight of chromium oxide (Cr2O3),
- more than 0.5% and less than 3% by weight of silica, and
- at least 1% by weight of zirconium oxide, with at least 20% by weight of said zirconium oxide (ZrO2) being stabilized in the cubic and/or quadratic form.
A gasifier internal refractory coating composition having at least one region of a sintered material containing chromium oxide (Cr2O3) and at least 1% by weight of zirconium oxide, at least 20% by weight of said zirconium oxide (ZrO2) being stabilized in the cubic and/or quadratic form, wherein the content of chromium oxide (Cr2O3) is greater than 80% by weight.
A gasifier internal refractory coating composition having at least one region of a sintered material containing
- at least 45% by weight of chromium oxide (Cr2O3),
- at least 1% by weight of zirconium oxide, at least 20% by weight of said zirconium oxide (ZrO2) being stabilized in the cubic and/or quadratic form, and
- at least Y2O3, not stabilizing the zirconium oxide.
