目前，在市面上的蜂窝陶瓷产品主要有刚玉陶瓷、莫来石陶瓷、堇青石陶瓷、锂长石陶瓷等材质。在蜂窝陶瓷行业，因其中是多孔陶瓷，由于孔隙的存在会降低产品强度，为了提高蜂窝陶瓷的烧结程度，有的企业使用添加钠长石、方解石等来降低其烧成温度，但其成瓷后，产品较碎，易损坏，不耐压，使用寿命短。
发明内容
本发明为了提高其成品机械强度，在国家倡导节能减排的形势下，为了提高产品竞争力，研制出一种高钾堇青石蜂窝陶瓷坯料，则能实现：一是降低温度烧成，同时保证其瓷化程度，二是能保证其足够的机械强度，三是能保证其最大化的蓄热能力。
本发明的目的在于引入了高钾熔块，加入到堇青石蜂窝陶瓷坯料中，使其氧化钾含量≥6%，既有效地降低了蜂窝陶瓷烧成温度，实现快速烧成，降低能耗，又提高了蜂窝陶瓷材料的致密度，不但大幅度提高蜂窝陶瓷机械强度，还大大增强了其蓄热能力。同时还具有耐高温、抗腐蚀、热稳定性好、导热性能好等显著优点，产品各项指标完全能够满足工业炉的使用及运行要求。此产品广泛的应用于化学工业、
