High alumina products can be classified into shaped and unshaped products. Shaped products refers to those with certain shape, viz, alumina ball, alumina bricks. And unshaped products, also called monolithic products, are cement, concrete, and mortar. Rongsheng Refractory Co., Ltd provide a whole range of alumina refractory products, including:
High alumina refractory products are made from bauxiteAl2O33H2Oor industrial alumina oxides, alumina in high alumina refractory products, refer to alumina oxides. Alumina oxides have extremely high melting point of 2054, boiling point 2980. It is a high hardness compound, which have excellent high temperature performance. Refractory Bricks and other refractory products made from alumina oxides can bear high temperature, resist slag erosion, has a good thermal shock resistant, abrasion assistant, good refractory under load performance, fine compressive strength, low linear change on reheating, dense crystal structure, low apparent porosity, etc.
Rongsheng, a professional High Alumina Refractory materials manufacturer in China, exports all kinds of cheap high alumina refractory productstoKorea, Japan, Vietnam, Pakistan, India, Indonesia, Malaysia, Nepal, Singpore, Taiwan, Greece, Spain, South Africa, Ethiopia, Jordan, Russia, Syria Ukraine and Laos and etc.

Bricks are the ubiquitous and versatile building material that provides the structure to many buildings, walls and decorative installations. As classic as they are common, the standard red brick varies in size by country and is used virtually everywhere. Of the many varieties of brick, clay bricks are by far the most common but others such as concrete bricks, mud bricks and others all form part of the building ecosystem for various applications.
Manganese umber refers to a broad range of manganese oxides, which are compounds with a broad applicability in pigmentation applications, in addition to having a wide variety of uses well beyond being a source of manganese metal. In addition to the rich brown colourations provided by these pigments - supplied by African Pegmatite - some added benefits such as easier handling and longer brick lifetimes are possible. When used in clay bricks, the depth of colour is viewed as excellent with a superior surface finish. A distinct benefit of the use of manganese umbers is that brick firing temperatures can be elevated - as high as 1,280 C - at which temperatures other bricks would vitrify and become unstable.
Firing stability for manganese umber is good, and normal brick and ceramic firing temperatures are comfortably tolerated up to 1,280 C. If firing above 1,150 C is available, this is preferential, as it means less manganese umber needs to be used to achieve the same colour profile.
K37 is best suited for use in clay bricks at the standard firing temperature of 1,130 C, including and especially for red clays. K37B is a developed variant of the K37 pigment that is optimal for use at lower firing temperatures around 1,080 C - particularly useful for regions with less stable or poorer quality clays.
