Refractory Fire clay powder
Brief:
Greenergy Refractory Fire clay powder, referred to as refractory soil. Fire clay powder with a refractoriness higher than 1580°C, the main component is aluminium silicate minerals, which are generally gray to yellowish red, and vary with the impurities (such as iron oxide) contained. And water is plastic, after drying and calcining, it becomes a dense mass.
What is refractory mortar?
Greenergy refractory mortar is a specially-engineered blend of specific cements and aggregates that gives the mortar unique heat-resistance and thermal characteristics for use in high-temperature applications such as chimneys, fire pits, barbeques, and pizza ovens. This mortar is used to bond fire brick or clay flues to each other. Ordinary mortars can be destroyed or deteriorate under such high-heat conditions.
